If a person is holding a rock over their head how much work is being done on the rock?

Answer»

- This is because the distance is ZERO. If someone is USING FORCE to HOLD a rock over their head while walking eastward across a field no work has occurred. This is because the force is not in the same DIRECTION ( the force is up) as the distance moved by the rock ( eastward) .
