Kinetic energy is energy of an object due to its motion. All types of energy can be transformed into other types of energy. This is true for potential and kinetic energy as well. When a car is in motion, it has kinetic Energy, when it hits another vehicle, the kinetic energy of the car is converted into heat energy, potential energy etc. Kinetic energy can also be converted in electric energy, Eg in case of Hydro electric generation, the kinetic energy of water is used to rotate the wings of the motors, that creates Electric Energy.
