Skateboard Ramp

Potential and Kinetic Energy

This concept design for potential and kinetic energy was a first take at a larger scale participatory lesson. The students strapped a Android based phone to a skate wheel car and took measurements as the car oscillated up a down each side.

The first attempt at this ramp was not terribly successful. I will need to add rails on the side to keep cars from veering off the ramp. Also, the ramp was not quite sturdy enough for a Skateboard.

The lesson can be as simple as dominoes on inclined planes.
