# How does gravity work without consumption of energy?

To move any stationary object a force has to be applied and applying force needs energy. So how are objects pulled towards each other by gravity without any use of energy?

Your premise that no energy is involved is false. Two point masses, with masses $M$ and $m$, separated by a distance $r$, have a gravitational energy associated with them given by: $$U=-{GMm\over r}$$
