Question

How does conservation of energy work?

Answer 1

, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be conserved over time. This lawmeans that energy can neither be created nor destroyed; rather, it can only be transformed or transferred from one form to another

Answer 2

The law of conservation of energystates that energy -- the ability to do work -- can't be created or destroyed. ... After the ball is released, its potential energy is converted into kinetic energy during its fall because of the work gravity does on it.
