A75.0 kg man is riding an escalator in a shopping mall. the escalator moves the man at a constant velocity from ground level to the floor above, a vertical height of 4.60m. what is the work done on the man done by gravitational force?

Contrast the force of gravity between these pairs of objects a 1 kg mass and a 2 kg mass that are 1 m apart and two 2 kg masses that are 1 m apart
