Hamsters have tons to do with physics. Their food has chemical potential enegy and they eat it. If you drop a hamster (which I do not reccomend) the total mechanical energy will remain the same. When a hamster runs on its wheel it creates thermal energy. As a hamster falls freely, the kinetic energy will increase and the potential energy will decrease. When a hamster is running if it doubles its speed the kinetic energy of the hamster will be quadrupled. A hamsters gravitational energy depends on its position with respect to earth. Hamsters have lots of energy.
