Investigate collisions on an air hockey table. Collision Lab can help you to set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum conserved? Is kinetic energy conserved? Vary the elasticity and see what happens.

Sample Learning Goals
1. Draw "before-and-after" pictures of collisions.
2. Construct momentum vector representations of "before-and-after" collisions.
3. Apply law of conservation of momentum to solve problems of collisions.
4. Explain why energy is not conserved and varies in some collisions.
5. Determine the change in mechanical energy in collisions of varying "elasticity".
6. What does "elasticity" mean?
