➠ The energy possessed by a body due to its motion is called as kinetic energy.

➠ William Thompson coined the term ‘kinetic energy’.

➠ Kinetic energy is depended on both motion and mass of a body.

➠ Five types of kinetic energy are :- radiant energy, thermal energy, sound energy, electrical energy and mechanical energy.

➠ Kinetic energy is the energy of motion.

➠ An object with greatest movement has most kinetic energy.

➠ Example: A walking person.
