This study guide on gravitation covers some key vocabulary, Kepler's Laws of Planetary Motion, and orbiting bodies or satellites. Includes important equations. It is available for download with free registration.

The student will investigate Hooke's law and the position, velocity and acceleration of an object oscillating vertically on a spring.

Students' use a motion detector to examine how different types of motion affect the shape of the distance versus time plot. They explore how changes in direction and other factors affect the shape of the plot.

Are you a piano player or a video gamer? Then you might have a quick reaction time that can come in handy while playing sports. Find out how to measure your reaction time and compare it to your friends and family with this fun experiment.

The motion of three simple harmonic oscillators is animated to illustrate the effects of mass and spring constant upon the motion. Several equations and a lengthy discussion accompany the animations.

A series of graphics, downloadable animations and text describe and explain the motion of a pendulum. Some sections require an understanding of calculus.
