PhysicStuff

PhysicStuff turns physics into something you can watch and then play with. Every video is built from a real simulation: the light rays, angles and numbers come from the same equations you'll meet in AP Physics, A-Level, the Leaving Cert, JEE and NEET.

Each topic has a free interactive version at physicstuff.com: drag the angle, change the material, and see the physics respond.
