In physics, the law of conservation of energy states that the total energy of an isolated system remains constantit is said to be conserved over time. Nuclear fusion is the process by which nuclear reactions between light elements form heavier ones, absorbing huge amounts of energy. The law of conservation of energy was first formulated by French physicist Antoine Lavoisier in 1789. In physics, the law of conservation of energy is used to analyze the behavior of systems and predict the outcome of interactions between them. All matter in the universe is made up of atoms, and all atoms have energy. The particle he conceived was a photon, and he speculated that when electrons within matter collides with photons, the former takes the latters energy and flies out. # Electric Power Systems 1p When you let go of the stretched band, that stored potential energy is quickly converted into kinetic energy as the band snaps back to its original shape. entertainment, news presenter | 4.8K views, 28 likes, 13 loves, 80 comments, 2 shares, Facebook Watch Videos from GBN Grenada Broadcasting Network: GBN News 28th April 2023 Anchor: Kenroy Baptiste.
