Because work is done against the gravitational force of the Earth.

Vedclass · Answer

(A) When an object is raised above the surface of the Earth,work must be done against the gravitational force exerted by the Earth.Since the displacement is in the direction opposite to the gravitational force,the work done by the gravitational force is negative.According to the work-energy theorem,this work done against the conservative gravitational force is stored in the system as gravitational potential energy.Therefore,the potential energy of the object increases as its height above the Earth's surface increases.

Why does the potential energy of an object increase when it is raised above the surface of the Earth?
