Item NG004004: Gravitational potential energy is transformed into motion energy as a rock falls from a cliff.
A rock falls from a cliff to the ground below. As it falls, its speed increases. Is energy transformed while the rock is falling? Explain.
- Yes, kinetic energy (motion energy) is transformed into gravitational potential energy as the rock falls.
- Yes, gravitational potential energy is transformed into kinetic energy (motion energy) as the rock falls.
- No, because the rock lost all of its gravitational potential energy once it started to move.
- No, because one form of energy cannot be transformed into another form of energy.
