Quick preparation for the exam in physics. Competent preparation for the exam in physics: how to get an excellent result

Instruction

Imagine a huge cake with lots of cream, biscuit and chocolate. So, learn physics quickly - the same as quickly eating this cake: everything seems to be delicious, fine, but if you try to swallow it whole and right away, you won’t digest it. Worse than that- will come out. Therefore, try your time so as to gradually eat a small piece and not allow dangerous satiety.

Since physics relies on , you must be fluent in mathematical apparatus. If in the process of studying physics some mathematical gaps are found, try to fill them, otherwise it will be difficult to understand the physical material.

physical system concepts are not as strict as in, so you can study theory and practice at the same time. Unlike dry mathematics, natural Sciences require creativity, active work imagination and consideration of the "psychology" of science itself. Any phenomenon of physics is not some abstract thing, but quite real event.

Write on separate pieces of paper the meaning of the terms you are entering, their physical meaning. Clearly distinguish one concept from another, but at the same time build relationships between them. For example, power is the work done per unit of time. Remember the formula for work and substitute it into the formula for power.

Complete all recommended courses laboratory works, arrange them as required. As a rule, in technical universities they put on only if you have passed all the “labs”. For each topic, solve fundamental problems, including qualitative ones.

Compiling cheat sheets will help you study the subject. This will allow you to quickly cover all the key points, systematize and summarize your knowledge. It is not recommended to use cheat sheets on the exam itself: this will confuse you and, if unsuccessful, set the teacher against you.

Physics studies the most general patterns the existence of the material world. Everything that happens in nature is the result of the action of certain forces. Studying these forces, you can simply try to memorize a list of them. But another approach is more correct - through an understanding of what and why is happening in the world around us.

Instruction

There are two training options. In the first case, a person mechanically memorizes various truths, his the main task is to be able to answer the questions of the teacher, pass the exams. This option does not give the main thing - understanding, so the knowledge gained is very fragile and quickly forgotten. But there is also the right way where knowledge is acquired not through memorization, but through understanding the material being studied.

For fast and lasting memorization existing forces it is necessary to find their concrete actions. For example, thrown objects fall down - these are the effects of gravity. In addition, all objects have weight, which is also nothing more than a consequence of gravitational influence. If a person, for example, is 70 kg, then this means that he acts on a support (floor, ground, platform) with just such a force that arises in the gravitational field of the Earth.

It is logical to assume that gravity will be different on another planet, so the weight will also be different. What will it be equal to? The weight of a body is equal to its mass times its acceleration. free fall. Free fall acceleration is measured per second and will vary from planet to planet. For example, for the Earth it is equal to 9.8 meters per second in, and for the Moon it is already only 1.6. Free fall acceleration characterizes the force with which the planet attracts bodies. Please note that mass does not characterize the weight of the body, but its measure of inertia. Under conditions of weightlessness, bodies weigh nothing, since there is no gravity. But in order to move them from their place, it is necessary to apply a certain force. The more massive the body, the greater this force must be.

Imagine how the weight of a person will change on different planets, you can easily and quickly learn the concept of gravity, deal with weight, mass, acceleration and other concepts of this topic. A coherent logical understanding of the ongoing processes will appear, while the material being studied will not have to be memorized by force, it will be remembered as it is studied. And all because you understand the essence of the phenomenon, understand what, how and why is happening.

Using this principle, you can quickly study other forces that exist in nature. For example, to study electromagnetic interaction, you need to understand how electricity along the conductor, what fields are formed in this case, how they interact, etc. Once you figure this out, you'll understand how it works. Electrical engine why the light bulb is on, etc. etc.

When studying forces, be sure to understand how they are interconnected, what they influence, what processes occur in the world under their influence. Knowing this, you can easily tell the teacher about this or that force, citing concrete examples. Even if you forget some formula when answering, it is unlikely to lower your score. It is important for the teacher to understand the material you are studying, and the formula for specific calculations can always be found in the reference book.

Books for preparing for the exam in physics

They will help you prepare for the exam. Such books contain many tasks of various levels of complexity from various areas mechanics, molecular physics, as well as from the field of electrodynamics and other areas school physics. Usually books are made in the form of a problem book or textbook. If this test tasks in physics - then you can find 3 parts ready dough. The first part is tasks with a short answer, then comes the second part with more complex tasks, which implies an even longer and more detailed justification for the answer. Also this part has tasks for understanding various laws and the ability to explain physical phenomena.

Still in the books go difficult tasks, which require explanations and analysis of processes from the field of physics and phenomena, but there may be tasks and requirements to solve difficult problems with numerous numerical calculations. Many tasks require the student to perform calculations on paper.

For the physics exam itself, you can take a ruler and a small non-programmable calculator with you to calculate trigonometric functions.

Formulas for preparing for the exam in physics

There are several hundred of them and many of them are worth learning by heart. In order to know the formulas, you need to visit specialized sites and prepare for the future exam, including on these sites. You can learn formulas in a system along with solving problems, or you can do this separately. In any case, the choice is yours.

Video tutorials aimed at knowing the formulas are also suitable.

Preparation courses for the exam in physics

There is on the Internet great amount courses that are aimed at preparing for the exam in physics from scratch. Recommended authors from the literature: Yakovlev, Gromtseva and Demidova.

Standard courses in physics include:

Individual work with the student and analysis of his knowledge. Real courses in the classroom, they can also take place as part of small group(5-6 people).
The most optimal program for preparation is from zero to 80 or more points.
Physics classes should be held on average 2 hours per week.

Only in this way can you best understand the five-year-old school course in physics and come to the exam at the maximum of your abilities.

The courses should also include ongoing work trainings and methodological examinations. These activities are the best way to consolidate the material already covered.

Sites for accelerated preparation for the exam in physics can be found in the list below

1. The place of honor is occupied by the USE Internet group / ege100ballov - it publishes the latest information about future training for the exam and the latest news, a daily analysis of solutions and assignments for the exam is carried out, the multiple theory of solutions is analyzed and tasks are analyzed.

There is also a solid database of video materials on the topic of preparing for the future exam.

2. The best channel on YouTube
/UCLDpIKDTFBSwIYtAG0Wpibg

This channel contains about 1000 video reviews of tasks in physics and solutions to them. Everyone who wants to prepare for the exam in physics should go to this channel and get acquainted with the video lessons.

3. As for the quality preparation for the exam in physics, the famous Reshuege website from Dmitry Gushin is one of the best in preparation.
This site has an open list of available tasks with solutions and analysis on the cover of tasks.

4. Site of Alexander Larin - for intensive training New variants and solutions of problems in physics are published here. detailed reviews. The site itself has many interesting sections and other materials with an explanation.

Passing the exam is one of the most important points in the life of any student. Exams are not only the basis for issuing a certificate, but also a pass to universities for further education. It is from this step that many begin to form the foundation of a successful career.

The physics exam is optional - it is optional. Such a test must be passed by those who are going to apply to technical university. However, this is one of difficult exams preparation for which must be especially thorough. The difficulty lies in several points. The first is a significant amount educational material. The subject is studied at school for five years and includes several areas (thermodynamics, mechanics, relativity theory and others). The situation is further complicated by the need to solve problems. It is not enough just to master the theoretical information - it must be applied in practice. To do this, you need to fill your hand and have good experience work with tasks different levels difficulties. It is these tasks that form the basis of a successful passing the exam in physics.

Another difficulty is the connection with mathematics, which is very important in this case. To solve problems in physics, you need a good mathematical foundation.

From the above difficulties, it becomes clear that full preparation to the exam in physics will take at least one year. A few months will not be enough to grow to the required level. The stumbling block here is also the fact that only classes at school are often not enough for high-quality and comprehensive training. Be sure to resort to additional tools that will better help in this matter.

How to prepare for the exam in physics

A typical mistake of schoolchildren and their parents is to rely on self-training fully. Even if the most talented student spends the whole day reading books, final result may not be happy. The reason is simple: physics is complex and complex science. Good preparation starts from scratch. This means that you need to re-work the entire course, fill in the gaps and bring knowledge into the system. All this should take place against the background of constant practice and regular solving of various problems. To achieve the result, it is necessary to work with a teacher who will help to deal with difficult questions, adjust classes, identify strong and weak sides student. school teachers, unfortunately, they cannot give all this, if only because they work with the whole class and simply do not have the opportunity to conduct individual work. Yes and time schoolwork severely limited.

Another option often chosen by students and parents is preparation for exam in physics with the help of a tutor. This option is not bad if you can find a good teacher, to whom it is convenient to go to classes. However, one must understand: excellent tutors are worth their weight in gold, it is not always possible to find one in a particular locality. Moreover, classes are often quite expensive, and the student himself has to spend a lot of time on the road. As a result, fatigue accumulates, the material is more and more difficult to assimilate, and preparing for the exam turns into no less stress than the exam itself. Not every student can withstand such a rhythm. However, there is a better alternative.

Online courses are becoming more and more popular these days. Various virtual schools offer their services on the most favorable terms. Thanks to this diversity, preparation for the USE exam in physics takes place in a more comfortable environment. The student can study at any convenient time, while he always has the opportunity to communicate online with the teacher. No extra stress, no time wasting - just combining all the benefits of tutoring and self-study..

Preparing for the Unified State Examination in Physics along with the site: effective, convenient, affordable

On the site, students will find everything they need to prepare for such a difficult exam. And to start preparing for the exam in physics is very simple: just register and pay for access to classes. These are the bonuses that will be appreciated by every student from the first lessons.

The ability to send a question to the tutor at any time via text chat.
Only experienced, qualified teachers who constantly confirm their high level.
The presence of a huge database of materials: notes, video lessons, homework based on USE past years.
A system for checking your own knowledge: the site provides special simulator programs, intermediate and final tests to consolidate the material, identify gaps in knowledge.
Sophisticated control system. All assessments are recorded in a convenient online journal, in addition, there is a mailing list with notifications of the most important events.

The most important advantage can be called the cost of classes. One month of training will cost users the same amount (or even less) as one lesson with a tutor. This is a great solution for those who, for some reason, save money. According to the site's program, full preparation for the exam in physics is about 240 hours - this is 60 lessons. During this time, you can reach a level that will allow you to successfully pass the exam and enter the chosen university.

Getting ready for the exam in physics: we use all the possibilities!

The exam should not cause fear, no matter how difficult the preparation may seem. Practice shows that students who conscientiously approached learning achieve good results. As in any business, work is also rewarded in this. And you can right now, especially since online courses are available all the time. Relying on the help of a teacher, using all available manuals and devoting enough time to self-preparation, you will definitely be able to achieve your goals.

If you are going to apply for technical specialties, then physics is one of the main subjects for you. This discipline is far from being given to everyone with a bang, so you will have to practice in order to cope well with all the tasks. We will tell you how to prepare for the exam in physics if you have a limited amount of time at your disposal, and you want to get the best possible result.

The structure and features of the exam in physics

In 2018 USE year in physics consists of 2 parts:

24 tasks in which you need to give a short answer without a solution. It can be an integer, a fraction, or a sequence of numbers. The tasks themselves are of various levels of complexity. There are simple ones like: maximum height, on which a body of mass 1 kg is lifted, is 20 meters. To find kinetic energy at the moment immediately after the throw. The solution does not a large number actions. But there are also such tasks where you have to break your head.
Tasks to be completed with detailed explanation(recording the condition, the course of the decision and the final answer). Here all the tasks are enough high level. For example: a cylinder containing m1 = 1 kg of nitrogen exploded during a strength test at a temperature of t1 = 327°C. What mass of hydrogen m2 could be stored in such a cylinder at a temperature of t2 = 27°C, with a fivefold safety margin? Molar mass nitrogen M1 = 28 g/mol, hydrogen M2 = 2 g/mol.

Compared to last year, the number of tasks increased by one (in the first part, a task was added to know the basics of astrophysics). There are 32 tasks in total that you need to solve within 235 minutes.

This year, students will have more tasks

Since physics is a subject of choice, the USE in this subject is usually purposefully passed by those who are going to go to technical specialties, which means that the graduate knows at least the basics. Based on this knowledge, you can score not only the minimum score, but also much higher. The main thing is that you prepare for the exam in physics correctly.

We suggest that you familiarize yourself with our tips for preparing for the exam, depending on how much time you have to learn the material and solve problems. After all, someone begins to prepare a year before the exam, someone a few months, but someone remembers the exam in physics only a week before the exam! We will tell you how to prepare in a short time, but as efficiently as possible.

How to Prepare Yourself A Few Months Before Day X

If you have 2-3 months to prepare for the exam, then you can start with the theory, as you will have time to read and assimilate it. Divide theory into 5 main parts:

Mechanics;
Thermodynamics and molecular physics;
Magnetism;
Optics;
Electrostatics and direct current.

Work through each of these topics separately, learn all the formulas, first the basic ones, and then the specific ones in each of these sections. You also need to know by heart all the values, their correspondence to one or another indicator. This will give you theoretical basis in order to solve both the tasks of the first part and the tasks from part No. 2.

After you learn to decide simple tasks and tests, go to more difficult tasks

After you've worked through the theory in these sections, start solving simple problems that take just a couple of steps to use the formulas in practice. Also, after a clear knowledge of the formulas, solve tests, try to solve them maximum amount not only to reinforce their theoretical knowledge, but also to understand all the features of tasks, learn to correctly understand questions, apply certain formulas and laws.

After you learn how to solve simple tasks and tests, move on to more complex tasks, try to build the solution as competently as possible, using rational ways. Solve as many tasks from the second part as possible, which will help you understand their specifics. It often happens that the tasks in the exam are almost the same as last year, you just need to find slightly different values or perform the reverse actions, so be sure to look at the exam for the past years.

The day before delivery USE is better give up solving problems and repetition and just relax.

Start preparing one month before the test

If your time is limited to 30 days, then you should follow these steps to successfully and quickly prepare for the exam:

From the above sections, you should make a pivot table with basic formulas, learn them by heart.
Browse typical assignments. If among them there are those that you solve well, you can refuse to work out such tasks by devoting time to “problem” topics. It is on them that the emphasis should be placed in theory.
Memorize the basic quantities and their meanings, the order of transferring one quantity to another.
Try to decide as best as you can. more tests, which will help you understand the meaning of the tasks, understand their logic.
Constantly refresh your knowledge of the basic formulas in your head, this will help you score good points in testing, even if you don’t remember complex formulas and laws.
If you want to take a swing at enough high results, then be sure to check out the past exams. In particular, focus on part 2, because the logic of the tasks can be repeated, and knowing the course of the solution, you will definitely come to the right result! It is unlikely that you will be able to learn how to build the logic of solving such problems on your own, so it is desirable to be able to find common ground between tasks previous years and the current task.

If you prepare according to such a plan, then you will be able to gain not only minimum scores, but much higher, it all depends on your knowledge in this discipline, the base that you had before the start of training.

A couple of quick weeks to memorize

If you remembered taking physics a couple of weeks before the start of testing, then there is still hope to score good points if you have certain knowledge, and also to overcome the minimum barrier if you are completely 0 in physics. effective training The following work plan should be followed:

Write down the basic formulas, try to remember them. It is advisable to study well at least a couple of topics from the main five. But you should know the basic formulas in each of the sections!

It is unrealistic to prepare for the Unified State Exam in physics in a couple of weeks from scratch, so do not rely on luck, but cram from the beginning of the year

Work with the Unified State Examination of previous years, deal with the logic of tasks, as well as typical questions.
Try to cooperate with classmates, friends. When solving problems, you can know one topic well, and they are different, if you just tell each other the solution, you will get a quick and effective exchange of knowledge!
If you want to solve any tasks from the second part, then you'd better try to study last year's USE, as we described when preparing for testing in a month.

If you fulfill all these points responsibly, you can be sure that you will receive the minimum allowable score! As a rule, on more people who started training a week in advance and do not count.

Time management

As we said, you have 235 minutes to complete the tasks, or almost 4 hours. In order to use this time as rationally as possible, first complete all simple tasks, the ones you least doubt from the first part. If you are good friends with physics, then you will have only a few unsolved tasks from this part. For those who started training from scratch, it is on the first part that the maximum emphasis should be placed in order to score the necessary points.

Proper distribution of your time and energy during the exam is the key to success

The second part requires a lot of time, fortunately, you have no problems with it. Read the tasks carefully, and then do the ones that you are best at first. After that, move on to solving those tasks from parts 1 and 2 that you doubt. If you do not have much knowledge in physics, the second part is also worth at least reading. It is quite possible that the logic of solving problems will be familiar to you, you will be able to solve 1-2 tasks correctly, based on the experience gained when viewing last year's USE.

Due to the fact that there is a lot of time, you do not have to rush. Carefully read the tasks, delve into the essence of the problem, only then solve it.

So you can prepare well for the exam in one of the most difficult disciplines, even if you start your preparation when testing is literally “on the nose”.

Preparation for the exam in physics. The most important recommendations.

But, firstly, you need to understand that you need to prepare for the exam not the day before, but in advance.

I recommend even starting preparation from the 10th grade. Why from 10th grade? Because from the 10th grade there is a repetition and systematization of important sections physicists-mechanics, molecular physics and electrodynamics. If you are late, you can start from September 11th grade. But by no means since the spring of the 11th grade.

Briefly tell USE structure in physics.

There are 31 tasks in total.

In the first part - 23 tasks.

The first 7 tasks are devoted to mechanics.

1 task - Find the kinematic value from the graph. Here we must remember the formulas for uniform and uniformly accelerated motion and represent them graphically.

2 task associated with finding power.

3 and 4 task - about mechanical work, equilibrium condition, energy.

5 task - out of 5 statements, choose 2 correct ones. This task is usually difficult.

6 task - how one or another value will change if another value is changed.

7 task

8 - 12 tasks - relate to molecular physics and thermodynamics:

8 - 10 task solve simple problems.

11 task - choose 2 true statements.

12 task - establish correspondence.

Basically, here you need to know the Mendeleev-Clapeyron equation, the Clapeyron equation, isoprocesses, the first law of thermodynamics, the amount of heat, efficiency heat engine, introduce graphic image isoprocesses.

13 - 18 tasks - electrodynamics.

By 13 task be sure to know the gimlet rule (rule right hand), the left hand rule for determining the Ampère force and the Lorentz force. Not just to know, but to be able to apply to a given situation. In this task, we write the answer in a word or words: up, down, right, left, from the observer, to the observer.

14 task - often according to the scheme, determine the current strength, voltage, resistance, power, or the ratio of these quantities.

15 task - either associated with optics, or with electromagnetic induction(Grade 11) .

16 task - again choose the correct 2 statements out of 5.

17 task - how the electrodynamic quantity will change when another quantity changes.

18 task - match between physical quantities and formulas.

19 - 21 tasks - nuclear physics.

19 task usually to determine the numbers of protons, neutrons, nucleons, electrons.

20 task - on the photoelectric effect equation, which is easy to remember.

21 tasks - compliance with processes.

22 task associated with error. I want to note that here it is necessary to equalize the numbers after the decimal point. For example, in the answer we received 14, and the error of this value is 0.01. Then we write in response: 14,000.01.

AT 23 tasks usually investigate the dependence, for example, of the stiffness of a spring on its length. Therefore, we are looking for material, the weight of the cargo is the same, but the length is different. If you do all 1 part without mistakes, you score 33 primary scores, or 62 points.

In the second part, the first 3 tasks are still filled in form 1, for which 1 point is given.

24 task - a task for mechanics,

25 task - task for molecular physics and thermodynamics,

26 task - a task for electrodynamics, optics.

If you solve them, you will score 69 points already. That is, if you do not proceed to form No. 2, you are already gaining 69 points. For some, this is a very good score.

But basically, you're going to make a mistake somewhere, so let's move on to part 2. What I call part C. There are 5 tasks.

From 27 - 31 tasks put 3 points each.

27 task - quality. This task must be painted, indicate what physical laws you used. Here, basically, you need to know the theoretical material.

28 task - difficult task on mechanics.

29 task - problem in molecular physics.

30 task - a difficult task in electrodynamics, optics.

31 tasks - task for nuclear physics.

Moreover, in form No. 2, it is necessary to paint all the formulas, all the conclusions, convert the units of measurement into SI units, make the correct calculation and be sure to write down the answer to the problem. It is best to derive the final general formula, substitute all units in SI, not forgetting the units of measurement. If received big number, for example, 56000000 W, do not forget about prefixes. You can write 56 MW. And in physics it is allowed to round in part C. Therefore, do not write 234.056 km, but you can simply write 234 km.

If you complete 1 complete task from the difficult part + part 1, you score - 76 points, 2 tasks - 83 points, 3 tasks - 89 points, 4 tasks - 96 points, 5 tasks - 100 points.

But it's really hard to get maximum score for the task, i.e. 3 points. Usually a student, if he decides, then gains 1-2 points. Therefore, I will say whoever scores 80 points is smart and well done. This is the man knowledgeable in physics. Because they give 4 hours for the whole exam.

The minimum threshold for physics is 9 primary points or 36 secondary.

Choose 2 correct statements out of 5, if 1 and 4 are correct, then you can write down both 14 and 41 in the form. If the assignment is for compliance, be careful here, the answer is the only one. If the task is to change the value, then the numbers can be repeated, for example, one and the second value increases, then we write 11. Be careful: no commas, no spaces. These assignments are worth 2 points.

It is not necessary to hire a tutor, you can prepare for the exam yourself. Now there are so many sites for preparing for the exam. Spend at least 2 hours a week on physics (who needs it). Who goes to tutors, he rarely sits on independent decision they think he gives them everything. They make a huge mistake though. Until a student starts solving problems on his own, he will never learn how to solve problems. Because with tutors, it seems that all tasks are simple. And no one will tell you during the exam, not even the idea of the problem. Therefore, after the tutor, be sure to decide for yourself, one on one with a book and a notebook.

If the student receives excellent grades in physics, this does not mean that he knows all physics, and he does not need to prepare for the exam. He is mistaken, because today he will answer, but tomorrow he may not remember. Real knowledge is close to zero. And it is necessary to prepare not some specific tasks, but to study physics completely. A very good problem book - Rymkevich. That's why I use it at school. Get a separate notebook for preparing for the exam. On the cover of your notebook, write down all the formulas that are used in solving problems. We passed mechanics at school, solve 1-7, 24, 28 tasks at once, etc. Very often when deciding physical tasks, you need to add vectors, degrees, apply the Pythagorean rule, the cosine theorem, etc. That is, you cannot do without mathematics, if you are not friends with mathematics, you can get a failure in physics. A week before the exam, review all the formulas and solved problems in your notebook.

I wish everyone to write as well as possible and be more confident after preparing for the exam. All the best!
