Here's a fun site that gives you insight and knowledge into the physics behind amusement parks.

When I was young(er) and in high school, I didn't really see how important physics was to everyday life. This might be part of the reason that the test roller coaster that I designed on this site was actually a thrilling ride - that is right up to the part where it would leave the track and plunge into the ground like a giant lawn dart.
