Replacements
Listings that take over the same core job as Step.
Algodoo
A 2D physics sandbox where you draw objects and watch them move, collide and interact.
Algodoo is a free draw-and-play 2D physics sandbox for macOS and iOS, simulating fluids, friction and optics, but it is not open source.
PhET Interactive Simulations
Free interactive physics, chemistry and math simulations usable directly in the browser.
PhET Interactive Simulations runs free in the browser with ready-made physics, chemistry and math simulations rather than experiments you build yourself.
