The majority of these virtual demos and lab activities originated from explorelearning.com and San Fransisco's Exploratorium. You are encouraged to click around and investigate. Some new additions come from the JavaLab at the University of Oregon.  For most of these you will need a java enabled browser or shockwave.

Projectiles

• Newton's Mountain- A tremendously high mountain with a cannon atop it. 
• Cannon (Ballistic simulator)- very simple and should run on most platforms
• Cannon v1.2 - much more involved and 4 different things to try, but very computer intensive (need IE)
• Sink the Pirates - a simplistic applets that allows you to modify velocity, angle, and g.
• Two Cannons - What happens when two cannons are aimed at each other?
• Destroy the Castle - Change parameters on a  medieval catapult to get the castle
