An object increases its energy when it raises to a height H. This is because work is done against gravity , it is also called gravitational potential energy.
EXPRESSION FOR GRAVITATIONAL POTENTIAL ENERGY:
Consider the mass of the object m which is raised through a height H from the ground floor to do this energy required Force - mg , work done - FS - mgh
Energy gained by object is mgh so the potential energy of the object is mgh .
hope that helps....!
