Moving Energy in a Toy Car

Ramp Flat on the Ground
Ramp lifted to ankles


Ramp Lifted to Knees



Ramp Lifted to Chest


"...each time you lifted the care you 'gave' the car more gravitational stored energy. Finally there was enough stored energy for the car to move down the ramp. When the car moved down the ramp, the gravitational stored energy was converted to kinetic energy...Since the toy car has more gravitational stored energy as it is lifted higher, there is more energy to convert to kinetic energy. As a result, there is more kinetic energy as the car goes down the ramp."
