ABSTRACT

According to the law of conservation of energy, energy cannot be made or destroyed but can be made to change forms. Moreover, when energy changes from one form to another, the amount of energy stays the same. Let’s consider an example of the law of conservation of energy: The initial energy of something is measured. The energy then changes from potential (stored) energy to kinetic (moving) and back again. After that, the energy is measured again. The energy measured at the start is the same as that measured at the end; it will always be the same. One caveat to this explanation is that we now know that matter can be made into energy through processes such as nuclear fission and nuclear fusion. The law of conservation of energy has therefore been modified or amplified to become the law of conservation of matter and energy.
