Potential energy of an object of mass m kept at a height h is mgh

The work done to lift this object against gravity to take it to a height h is  converted as Potential energy of this object.

Therefore,

work done = Force*distance
= Mass*acceleration*distance
= m*g*h
= mgh

therefore, Potential energy = mgh
