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.

  1. Yes, motion energy (kinetic energy) is transformed into gravitational potential energy as the rock falls.
  2. Yes, gravitational potential energy is transformed into motion energy (kinetic energy) as the rock falls.
  3. No, because the rock lost all of its gravitational potential energy once it started to move.
  4. No, because one form of energy cannot be transformed into another form of energy.
