    1. the law of conservation of energy states that the total energy of an isolated system in a given frame of reference remains constant — it is said to be conserved over time.[1] In other words, this law means that energy can neither be created nor destroyed.

    1. Conservation of momentum. So long as no external forces are acting on the objects involved, the total momentum stays the same in explosions and collisions. We say that momentum is conserved.

    1. First of all, saving energy is important because energy use effects the environment and everyone in it. Secondly, when you conserve energy you also save on the cost of living. replenished, such as water, wind, and solar. Nonrenewable energy sources, on the other hand, like gas, coal, and oil, cannot be replaced
