A toy car rolls down a high ramp and moves faster than a toy car rolling down a low ramp. What evidence does this provide about speed and energy?

Speed decreases as an object gains kinetic energy. Faster moving objects carry more energy of motion. Ramp height does not affect how fast a car moves. Energy disappears when a toy car stops at the bottom.

Correct Answer:

Faster moving objects carry more energy of motion.
