This book shows a simplified view of the design considerations and science a mechanical/civil design engineer must know when designing a roller coaster. It includes labs, assignments to be done at an amusement park, hands on design of a roller coaster, and more. Looks like 150+ pages of fun and physics.

This link is to the second article in a series about geostationary orbits (i.e. the orbit that allows communications satellites to remain at fixed points in the sky). The second article describes the geometry of the geostationary orbit. The series includes notes on antennas, pointing angles, Clarke, Kepler, etc.

These sites discuss the physics of gymnastics.

The site A Physics Interpretation of the Front Handspring Vault has annoying pop up menus but the site is worth it.
