State and prove law of conservation of energy.​

Answer 1

Explanation:

Law of conservation of energy states that the energy of a system is always constant. In other words, we can say that energy can neither be created nor destroyed. ... Mechanical energy (E) is the sum of the potential energy (U) and the kinetic energy (K) of the freely falling body. Therefore, E=K+U=constant.
