Drive the expression for potential energy |
| Answer» IMAGE or here is SHORT derivationLet 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 | |
