Step

            
            Interactive physical simulator for KDE

With Step you can not only learn but feel how physics works. You place somebodies 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 thelaws of physics. You can change every property of bodies/forces in yourexperiment (even during simulation) and see how this will change evolutionof the experiment.

This package is part of the KDE education module.
