Gravitational potential energy derivation. Writing a set of equations each with one or more variables eliminated will provide a set of. That is the bodys total energy is simply its classical kinetic energy 1 2 m 0 v 2 plus its rest energy.
Work transfers energy from one place to another or one form to another.
The work-energy theorem can be derived from Newtons second law. W DKE 1 2mv2 f 1 2mv2 i W D KE 1 2 mv f 2 1 2 mv i 2. Accordingly rotational kinetic energy is equal to one-half the product of the moment of inertia and the square of the angular velocity or 12Io2. Thus the energymomentum relation and both forms of the massenergy relation mentioned above all become the same.
