“Playing with Physics” apps allow interactive simulation of select physics phenomena.

The “Rolling on Inclined Plane” app simulates this motion depending on the specified input conditions. We can speed up, slow down or stop the movements at any time. Current values of physical quantities are displayed, it is possible to view them clearly in a table. For example, it is possible to find out at what inclinations of an inclined plane bodies with different moments of inertia will move with the same acceleration, as illustrated in the figure.
