From Kepler's planetary laws to standing waves, this collection of animations puts concepts from beginning physics and astronomy into motion. Creator Michael Gallis, a physics professor at Pennsylvania State University in Schuylkill, has gathered more than 100 brief movies in categories such as mechanics, electricity and magnetism, and optics. Students can stretch a cylinder to discover how to calculate Young's modulus of elasticity, follow the moon's orbit to learn why eclipses are so rare or see how interference between two waves that reflect off the walls of a container spawns a rippling pattern.
