Question: Two stones, one with twice the mass


Two stones, one with twice the mass of the other, are thrown straight up and rise to the same height h. Compare their changes in gravitational potential energy (choose one):
(a) They rise to the same height, so the stone with twice the mass has twice the change in gravitational potential energy.
(b) They rise to the same height, so they have the same change in gravitational potential energy.
(c) The answer depends on their speeds at height h.
