Work and Energy
... An object’s kinetic energy is energy of motion, is determined by its mass and speed. KE = ½ mv2. Potential energy and kinetic energy are forms of mechanical energy. In addition to mechanical energy, most systems contain non mechanical energy. Non mechanical energy does not usually affect systems on ...
