At the bottom of the track the car has kinetic energy only. The more potential energy a car has at the top the more kinetic energy it will have at the bottom, and the farther the car will go. Toy cars, racetracks and other toys with wheels are excellent for experimentation with potential and kinetic energy, acceleration and momemtum.
