It's one thing to learn about physics in a lab, but it can be quite another thing to make a pilgrimage to an amusement park to take in the laws of physics. Users will have to supply their own corn dogs and popcorn, but this rather nice educational resource from Annenberg Media will be quite useful for budding physicists and their teachers. The resource allows users to design their own roller coaster, and along the way they will learn a thing or two about the laws of gravity, pendulums, and kinetic energy. Along with explanatory essays, this resource contains interactive graphics and a glossary of terms. Sit back and enjoy the virtual roller coaster ride, as this site provides a rather novel way of introducing students to physics.
