Anil and Brij are hammering a nail into two pieces of wood to join them. Sunita covered her ears, because she said that hammering is noisy. She told them that they are wasting energy because most of the energy they used in hammering is getting lost. Anil disagreed with what Sunita said. Brij explained that some of the energy is converted to sound and heat, but not lost. Anil then added that energy can never be lost or destroyed.
