It is the energy possessed by a body or a system, for doing work, by virtue of its mass and velocity of motion. ![]() (b) When m is in kg and z in metres, then the potential energy will also be in N-m, as discussed below: We know that potential energy, 1 PE = m g z = kg x X m =N-m. Potential energy, PE = W z = m g z It may be noted that (a) When Wis in newtons and z in metres, then potential.energy will be in N-m. Let W Weight of the body, m Mass of the body, z Distance through which the body falls, and g = Acceleration due to gravity= 9.81 m/s2 For example, a body raised to some height above the ground level possesses potential energy because it can do some work by falling on earth's surface. It is the energy posse~ed by a body or a system, for doing work, by virtue of its position above the ground level. ![]() HiJio)llll &Distributors, Booksellers &Pubhohers ATcxtbookOfRcfrigcratlonA5aeed Book Bank lEW DELHI- 110055 S Kh KHURMI J.K.GUPTAĮURASIA PUBLISHING HOUSE (P) LTD.
