Question

state the law of conservation of energy? Give an example.

Answer 1

The law of conservation of energy states that energy can neither be created nor be destroyed, but it can be transformed from one form to another. So I considered an example of it as follows: water is stored at height with potential energy, the water flows and its potential energy is converted into kinetic energy.

Answer 2

energy can be neither created nor destroyed but it can be transferred from one body to another body . e.g one side of metal rod is heated then another side also get heated so, heat energy is tranfered .
