Proof of the formula for the kinetic energy of an object
... The energy possessed by a body by virtue of its motion called the kinetic energy of the body. A rocket traveling to the Moon has kinetic energy as does a snail crawling along a wall. It is the kinetic energy of objects that makes them difficult to stop and the kinetic energy of the air in a hurrican ...
