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

The “Compound Oscilations” allows us to simulate the composition of two or more oscillatory movements and displays the oscillations that will be created by the composition of the specified oscillations. When entering, the name of the oscillation, color, amplitude, frequency and initial phase can be set. Oscillations can be hidden and displayed again during the simulation. We can speed up, slow down or stop the simulation at any time. Current values of physical quantities are displayed, which can be clearly viewed in a table.
