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

The “Drag” app is intended to study the influence of the environment on a fall, a vertical throw, a horizontal throw and projectile motion. After entering the input conditions, where in addition to the throw parameters (initial coordinates, speed, elevation angle) we also choose the characteristics of the body (dimensions, shape) and the environment (gravitational acceleration, density), we can study up to five movements at once. 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.
