From where do the object 'lifted up' gets the energy?

Answers

Answered by samarthpawar48

Answer:

If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh . We define this to be the gravitational potential energy (PE g ) put into (or gained by) the object-Earth system.
