"WebBecause external forces are capable of changing the total mechanical energy of an object, they are sometimes referred to as nonconservative forces. When the only type of force doing net work upon an object is an internal force (for example, gravitational and spring forces), the total mechanical energy (KE + PE) of that object remains constant.
