Planetary Motion
This applet allows the user to create an orbit around the sun using Kepler's law. "Click anywhere on the applet to place your planet. Then drag to give it an inital velocity. Clicking on "Show Kepler's Law" will mark off the orbit in equal time segments for the next orbit created. Each segment created has the same area."
Relates directly to the GLE. Kepler's laws explain planetary orbits and gravity.
