Phun Teaches Physics Lessons the Best Way Possible

Windows/Mac/Linux (All platforms): Phun, a free open-source, cross-platform 2D physics simulator, makes you want to pick up blocks, or maybe crayons, and learn more about the way things fall and move under pressure. Written by a Swedish graduate student, the program teaches concepts of restitution and friction, so it’s great to load up with the kids, but you’ll probably find yourself sneaking a few turns by yourself at creating, and knocking over, shapes and lines. Phun is a free download for Windows, Mac OS X, and Linux systems; hit the link for instructions on using and having, well, fun in Phun.
