Would half the propellent energy from a gun or rocket be wasted on the kinetic energy of the gun's recoil or rocket's exhaust gases due to Newton's Third law and the Conservation of momentum. Newton says for every force there is a reactionary force so is it impossible to transfer the potiental energy into kinetic energy of a mass without moving something else and if so isn't that wasting energy. Thanks for your help.
