Moments of inertia for various bodies

Hundreds of free games illustrating basic principles of physics.

This site lets users see the relationships between kinetic energy, potential energy, friction, and gravity as they design a roller coaster.

A list of equations and constants for AP Physics B and C exams, organized by subject.

This website provides not only an explanation of how the ballistic pendulum can be used to measure the speed of a bullet but also a calculator to check your work. It can be used to explain a similar assembly involving a spring instead of a pendulum as well. You simply substitute the equation for the potential energy of a spring for (M+m)gd -- the potential energy of the pendulum.

This website contains information on the rotational motion and energy of a simple pulley-mass system. It also has math for a sticky rotational collision.

This describes (with equations and diagrams) the work-energy principle, and how it applies to rotation, including the important conditions for rolling without slipping.
