Does the centripetal force acting on an object do work on the object?
A. Yes, since a force acts and the object moves, and work is force times distance.
B. Yes, since it takes energy to turn an object.
C. No, because the object has constant speed.
D. No, because the force and the displacement of the object are perpendicular.
