If you're interested in the motion of planets in the solar system, try this Java applet for a demonstration of Kepler's Second Law. You'll see the time taken to sweep out equal areas on opposites sides of the orbit. You can change the semi-major axis and eccentricity of the orbit. There's also an option to show the velocity vector of the orbiting object. This applet is available in different languages and is part of a large collection of similar physics applets.
Please note that this resource requires
at least version 1.4.2 of
Java Applet Plug-in.
