WebThe principle of Conservation of Mechanical Energy. The total mechanical energy (E=KE+PE) of an object remains constant as the object moves, provided that the net work done by external non-conservative forces is zero, W nc =0J. Total mechanical energy: the sum of kinetic energy and gravitational potential energy. E = KE + PE.
