step - 4:22.12.3-1+b3 main

With Step you can not only learn but feel how physics works. You place some
bodies on the scene, add some forces such as gravity or springs, then click
"Simulate" and Step shows you how your scene will evolve according to the
laws of physics. You can change every property of bodies/forces in your
experiment (even during simulation) and see how this will change evolution
of the experiment.
