An object weighing 75N is dropped from the top of a building and falls 28 m how much work does gravity do?
- Chosen by Voters Work done by gravity is equal to the force acting on the object (its weight of 75 N) multiplied by the distance over which the force acts, 28 m in this case. So the work done by gravity is 75 * 28 = 2100 J. 4 weeks ago 100% 1 Vote
