Question

derive an expression for the potential energy of an object of mass 'm' raised to height 'h'

Answer 1

See, bro, work is always equal to force on the body and the displacement produced by that force in the body,
Now, if a body is placed at a particular height "h" of mass m
Then the weight of the body is the required force =m*accelartion due to gravity
Now , the body is placed at a height h,which is the required displacement here,
Therefore , potential energy of the body = mgh
Hope my explanation helps u,
Thanks you
