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

The “Projectile Motions” app enables the study of the gradual radioactive decay of selected important radioisotopes. The decay is represented by a running animation and at the same time a plot of the dependence of the relative decay of nuclei as a function of time is plotted. The application run is supplemented with a table of values. Furthermore, it is possible to extend the observation of the decay with animations showing the dependence of the activity of the radionuclide as a function of time. The rendering is again supplemented by a table of values. A Demo is attached to the application, in which animations describing the basic types of decompositions take place.
