A 5kg rock and a 10kg rock are dropped from a height of 10m. Which of the following statements describes what happens to the potential energy of the rocks?
a) Neither rock loses potential energy because no work is done on the rocks. b) Bother rocks lose the same amount of potential energy because they fall from the same height. c) The 10kg rock loses more potential energy than the 5kg rock because the 10kg rock falls faster. d) The 10kg rock loses more potential energy than the 5kg rock because the 10kg rock has more mass.
