Gears are used to increase and decrease rotational speed and according to this relation v = rω we can say that gears can increase and decrease kinetic energy. According to law of conservation of energy energy can only change its form. During gears working what will be the role of potential energy and how kinetic energy is converted in this potential when we increase and decrease gear speed?
