... falls.∴ Potential energy,P.E. = W. h = m.g.hIt may be noted that(a) When W is in newtons and h in metres, then potential energy will be in N-m.(b) When m is in kg and h in metres, then the potential ... view :1. Potential energy. It is the energy possessedby a body, for doing work, by virtue of its position.For example, a body raised to some height abovethe ground level possesses potential ... be in N-m as discussedbelow :We know that potential energy= m.g.h = kg × 2m×m=N-ms 21 kg-m1N =s32.
