A collection of simulations and virtual labs focusing key priniciples of physices. The simulations help students see how they can "play" with the principles of physics in a virtual lab. Two labs that were showcased at the PCUC meeting on August 21, 2012:
1. Learning the basics of potential and kinetic energy and add friction into the mix: skate-park-basics
2. Projectile Motion with Canons! Learn about trajectories of flying objects by shooting them out of a virtual canon.-motion
Both of these virtual labs are part of the Physics Collection http://phet.colorado.edu/en/simulations/category/physics
