This page contains demonstration OGE options in physics for grade 9 for 2009 - 2019.

Demo Options OGE in physics contain tasks of two types: tasks where you need to give a short answer, and tasks where you need to give a detailed answer.

To all the tasks of all demonstration options for the OGE in physics answers are given, and tasks with a detailed answer are provided detailed decisions and guidelines for scoring.

Some quests require you to collect experimental setup based on standard sets for frontal work in physics. We also provide a list of required laboratory equipment.

AT demo version of the OGE 2019 in physics compared to 2018 demo no changes.

Physics demo changes

Demonstration versions of the OGE in physics 2009 - 2014 consisted of 3 parts: tasks with a choice of answers, tasks with a short answer, tasks with a detailed answer.

In 2013 in demo version of the OGE in physics the following changes:

• It was added task 8 with a choice of answers- on thermal phenomena,
• It was added task 23 with a short answer– understanding and analysis of experimental data presented in the form of a table, graph or figure (scheme),
• It was the number of tasks with a detailed answer has been increased to five: task 19 of part 1 was added to four tasks with a detailed answer of part 3 - on the use of information from the text of the physical content.

In 2014 demo version of the OGE in physics 2014 towards previous year by structure and content did not change, however, were criteria changed evaluation of tasks with a detailed answer.

In 2015, there was variant structure changed:

• Option became be in two parts.
• Numbering assignments has become through throughout the variant without letter designations A, B, C.
• The form of recording the answer in tasks with a choice of answers has been changed: the answer has become necessary to write digit with the number of the correct answer(not circled).

In 2016 in demo version of the OGE in physics happened significant changes:

• Total Jobs reduced to 26.
• Number of short answer items increased to 8
• Maximum score for all work did not change(still - 40 points).

AT demo versions of the OGE 2017 - 2019 in physics compared to 2016 demo there were no changes.

MECHANICAL PHENOMENA.
mechanical movement. Trajectory. Way. Move.
Mechanical motion is a change in the position of a body in space relative to other bodies over time. Exist different kinds mechanical movement.

If all points of the body move in the same way and any straight line drawn in the body remains parallel to itself during its movement, then such a movement is called translational.
The points of a rotating wheel describe circles about the axis of this wheel. The wheel as a whole and all its points make a rotational movement.
If a body, for example, a ball suspended on a thread, deviates from the vertical position either in one direction or the other, then its movement is oscillatory.

The definition of the concept of mechanical motion includes the words "relative to other bodies". They mean that a given body can be at rest relative to some bodies and move relative to other bodies. Thus, a passenger sitting in a bus moving relative to buildings also moves relative to them, but is at rest relative to the bus. A raft that floats along the river is stationary relative to the water, but moving relative to the shore. Thus, speaking of mechanical movement body, it is necessary to indicate the body relative to which the given body is moving or at rest. Such a body is called a reference body. In the above example with a moving bus, a house, or a tree, or a pole near the bus stop can be chosen as the reference body.

Preparation for the OGE and the Unified State Examination

Main general education

UMK line A. V. Peryshkina. Physics (7-9)

Getting ready for the OGE in physics: task number 23

When preparing for the OGE, experimental task No. 23 raises the most questions. It is the most difficult, respectively, and the most time is allotted for it - 30 minutes. And for its successful implementation, you can get the most points - 4. This task begins the second part of the work. If we look into the codifier, we will see that the controlled content elements here are mechanical and electromagnetism phenomena. Students must show the ability to work with physical instruments and measuring instruments.

There are 8 standard sets of equipment that you may need for the exam. Which ones will be used becomes known a few days before the exam, so it is advisable to conduct additional training before the exam with the tools that will be used; be sure to repeat how to take readings from instruments. If the exam is held on the territory of another school, the teacher can arrive there in advance to see the kits ready for work. The teacher preparing the instruments for the exam should pay attention to their serviceability, especially those subject to wear. For example, using an old battery may result in the student simply not being able to set the required amperage.

It is necessary to check whether the devices match with specified values. If they do not match, then special forms indicate true values, and not those recorded in the official sets.

The teacher responsible for administering the exam can be assisted Technical Specialist. He also monitors compliance with safety regulations during the exam and can interfere with the progress of the assignment. Students should be reminded that if they notice a malfunction of any device during the assignment, they should report it immediately.

There are three types of experimental items found on the physics exam.

Type 1. "Indirect measurements physical quantities". Includes 12 themes:

• Matter density
• Strength of Archimedes
• Sliding friction coefficient
• Spring rate
• Period and frequency of oscillations mathematical pendulum
• Moment of force acting on the lever
• Work is the elastic force when lifting a load with a movable or fixed block
• The work of the friction force
• Optical power of converging lens
• Resistor electrical resistance
• Work of electric current
• Electric current power.

Type 2. "Presentation of experimental results in the form of tables or graphs and formulation of a conclusion based on the obtained experimental data." Includes 5 themes:

• The dependence of the elastic force arising in the spring on the degree of deformation of the spring
• The dependence of the period of oscillation of a mathematical pendulum on the length of the thread
• The dependence of the current strength arising in the conductor on the voltage at the ends of the conductor
• Dependence of sliding friction force on normal pressure force
• Properties of an image obtained with a converging lens

Type 3. "Experimental verification physical laws and consequences." Includes 2 themes:

• Law serial connection resistors for electrical voltage
• The law of parallel connection of resistors for the strength of electric current

Preparation for the OGE in physics: tips for the student

• It is important to be very precise in writing down everything that the rules require on the answer sheet. Checking your work, it is worth taking another look to see if anything is missing: schematic drawing, formula for calculating the required value, results of direct measurements, calculations, numerical value desired value, output, etc., depending on the conditions. The absence of at least one indicator will lead to a decrease in the score.
• Behind additional dimensions entered in the form, the score is not reduced
• Drawings must be done very carefully, sloppy schemes also take away a point. It is important to learn to control the indication of all units of measurement
• When writing down the answer, the student should not indicate the error, but it is worth conveying to him the information that the verifier has criteria and the correct answer already contains the boundaries of the interval within which the correct result may turn out.

Preparation for the exam in general and for experimental task in particular cannot be spontaneous. It is almost impossible to complete tasks without constantly developing skills in working with laboratory equipment. Therefore, teachers are advised to familiarize themselves with the demo options. examination work and disassemble typical tasks during the laboratory.
