  • A 5 kg rock and a 10 kg rock are dropped from a height of 10 m. Which of the following statements describes what happens to the potential energy of the rocks?

    Both rocks lose the same amount of potential energy because they fall from the same height.
    The 10 kg rock loses more potential energy than the 5 kg rock because the 10 kg rock has more mass
    The 10 kg rock loses more potential energy than the 5 kg rock because the 10 kg rock falls faster.
    Neither rock loses potential energy because no work is done on the rocks.
