Question

Describe the conversions from potential to kinetic energy, or kinetic to potential energy, as a toy car rolls down a ramp.

Answer 1

Answer:

When an object falls, its gravitational potential energy is changed to kinetic energy. You can use this relationship to calculate the speed of the object's descent. Gravitational potential energy for a mass m at height h near the surface of the Earth is mgh more than the potential energy would be at height 0.
