Nuclear Fusion

The origin of the energy released in fusion of light elements is because of interplay of a couple of opposing forces, the nuclear force which in turn combines together protons as well as neutrons, and the Coulomb force which in turn causes protons to repel one another. Nuclear fusion is a nuclear reaction in which some atomic nuclei occur very close and then collide at an incredibly high speed and join to create a new nucleus. Fusion is the process that properties active or “main sequence” stars.
