Ball A falls vertically 2.0 m, while an identical ball (Ball B) roles down a ramp of the same height. How does the work done by gravity on both balls compare?

A. Gravity does more work on Ball A because only a component of gravity accelerates ball B.

B. Gravity does the same amount of work on both because both balls undergo the same vertical displacement.

C. The work done by gravity on Ball B is greater because that ball travels a greater distance than ball A.
