Derive expression of potential energy.

Answered by admin @ 17/08/2021

Derivation for the equation of Potenstial Energy:

Let the work done on the object against gravity = W

Work done, W = force × displacement

Work done, W = mg × h

Work done, W = mgh

Since workdone on the object is equal to mgh, an energy equal to mgh units is gained by the object . This is the potential energy (Ep) of the object.

Ep = mgh
