Item NG004003: Gravitational potential energy is transformed into motion energy as a rock falls from a cliff.
Is energy transformed while a rock is falling from a cliff? Explain.
- Yes, motion energy (kinetic energy) is transformed into gravitational potential energy as the rock falls.
- Yes, gravitational potential energy is transformed into motion energy (kinetic 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.
