Examples:
(i) A moving hammer drives a nail into the wood. Being in motion, it has kinetic energy or ability to do work, as shown in Fig. 11.6.
(ii) A fast moving stone can break a window pane. The stone has kinetic energy due to its motion and so it can do work.
(iii) The kinetic energy of air is used to run windmills.
(iv) The kinetic energy of running water is used to run water mills.
(v) A bullet fired from a gun can pierce a target due to its kinetic energy.
