Required Equipment:

1. Computer with internet access.
2. Physics simulation software (e.g., http://efizika.ru/html5/04/index.html).
3. Virtual inclined plane.
4. Virtual objects (e.g., blocks or other bodies with different materials).
5. Virtual angle measuring tool.

Procedure:

1. Launch the simulation software: Open the physics simulation software on your computer. Make sure it provides the functionality to work with an inclined plane and measure angles.

2. Set up the experiment:

   • Create a virtual inclined plane with a specified angle of inclination.
   • Place virtual objects (blocks or other bodies) on the plane.
   • Select objects with different materials to investigate the coefficients of friction for different surfaces.

3. Measure the angle of inclination: Using the virtual angle measuring tool, accurately measure the angle of inclination of the inclined plane. This parameter is essential for subsequent calculations.

4. Perform the experiments: Gradually change the angle of inclination of the plane and place different objects on it. Record observations on the motion of the objects.

5. Calculate the coefficients of friction: Using the measured angles of inclination and the data on the motion of objects, calculate the coefficients of friction for each pair of surfaces. Pay attention to both static and kinetic coefficients of friction.

6. Estimate uncertainties: Consider measurement uncertainties when calculating the coefficients of friction. Think about possible sources of errors and their impact on the experimental results.

7. Compare with theory: Compare the obtained values of the coefficients of friction with theoretical values, if available. Draw conclusions about the agreement or discrepancy of the results with theory.

8. Prepare the report: Create a report on the completed virtual physics laboratory work, including the methodology, collected data, calculations, analysis of the results, and conclusions.

Please follow the instructions of the simulation software and perform the experiment carefully. Good luck with your virtual laboratory work!
