##### Product Description

The software package includes 10 virtual laboratory works from the general physics course for students of higher and secondary educational institutions:

- Uniformly Accelerated Motion;
- Motion with Uniform Acceleration;
- Laws of Collisions;
- Free Fall;
- Inclined Launch;
- Precession and Nutation of a Gyroscope;
- Rotational Motion with Uniform Acceleration;
- Moment of Inertia of a Horizontal Rod;
- Moment of Inertia of Various Test Bodies;
- Maxwell’s Wheel.

The virtual laboratory practice is implemented in the form of a set of cross-platform graphical applications supplied for various operating systems: Microsoft Windows, Linux, MacOS, iOS, Android, as well as web applications based on HTML5 technology, which provide the ability to remotely perform laboratory work in a web browser. The graphical component of the software uses the OpenGL 2.0 programming interface and component base.

**Note:** for best performance of online-versions of applications, we recommend using the Microsoft Edge web browser.

##### 1. Uniformly Accelerated Motion

Goals: study of uniformly accelerated motion of the body depending on the accelerating and accelerated masses.

##### 2. Motion with Uniform Acceleration

Goals: distance measurement depending on time; determination of velocity at any given moment in time; determination of acceleration at any given point depending on time; determination of the average acceleration according to the data.

##### 4. Free Fall

Goals: measuring the time it takes for the ball to fall to the distance between the release mechanism and the target below; plotting the distance/time diagram for uniformly accelerated movement; demonstration that the distance covered is proportional to the square of time; determination of the acceleration of gravity.

##### 5. Inclined Launch

Goals: measuring the width of the trajectory depending on the angle of throw and initial velocity; calculation of the initial velocity according to the maximum width of the trajectory; constructing along the points of a parabolic path depending on the angle of the throw.
