In the following interactive students will begin to understand the laws of Kepler regarding planetary motion and derive the third law of Kepler for circular orbits. They will also discuss the Ptolemaic model of the universe.

The three laws of planetary motion as described by Kepler are stated and elaborated upon. Useful graphics and an easy-to-understand language are used to explain the nature of planetary motion. Both conceptual and mathematical. Includes a...

The purpose of this task is to solve some expressions requiring fractional exponents in the modeling context of planetary motion. Aligns with N-RN.A.2.

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.

This site from NASA states Kepler's third law of motion and extends it to develop an equation for the velocity of an orbiting planet.
