Detailed explanation-1: -The law of conservation of energy states that energy can neither be created nor destroyed-only converted from one form of energy to another. This means that a system always has the same amount of energy, unless it’s added from the outside.

Detailed explanation-2: -According to the law of conservation of energy, energy cannot be created or destroyed, although it can be changed from one form to another.

Detailed explanation-3: -In mechanics, there are three fundamental quantities which are conserved. These are energy, momentum and angular momentum. If you have looked at examples in other articles-for example, the kinetic energy of charging elephants-then it may surprise you that energy is a conserved quantity.

Detailed explanation-4: -The First Law of thermodynamics is a formulation of the law of conservation of energy, adapted for thermodynamic processes. A simple formulation is: “the total energy in a system remains constant, although it may be converted from one form to another."

Detailed explanation-5: -Exact conservation laws include conservation of mass and energy, conservation of linear momentum, conservation of angular momentum, and conservation of electric charge.
