Satellite+Applet

Here is the applet: http://www.colorado.edu/physics/2000/applets/satellites.html

My applet is about satellite. It mainly talks about how satellite orbit around Earth. You can make a new satellite for Earth by clicking on anywhere of the applet. Be aware, if you only click on it, the satellite you create will crash straight into Earth, because the satellite's speed is 0, it will fall because of Earth's gravity. But if you click on the applet and drag the mouse at the same time, which gives the satellite a speed, it will probably be captured by Earth, and orbit around the Earth.

Here is the homepage of the applet, and it's the official site for the University of Colorado. It provides a lot of information about technology. A good site to visit.
