Try out these Java applets listed below (requires a Java enabled browser)!
Solar System: In this simulation you can control the masses, starting locations and initial velocities of five different planets in a computer-generated solar system. For more on orbits see Large Scale Effects Pages 4, 5, 6 and 7.
Kepler's Second Law: This is a modification of the Solar System applet which gives you an animated demonstration of Kepler's second law of planetary motion. For more on Kepler's second law see Large Scale Effects Page 6.
Pirates: Learn about ballistic motion with this game that lets you control a cannon on an old British sailing ship. For more on ballistics see Small Scale Effects Page 8.
Trampoline: Observe the balance in an object's potential and kinetic energy when it is launched into the air. For more on ballistics see Small Scale Effects Page 8
Surface Gravity: Have you ever wondered what you would weigh on the surface of Jupiter or Pluto? Now you can find out with this Java applet that calculates weights for every planet in our solar system. For more on surface gravity see Small Scale Effects Page 4.
