 In the Sun, the process of hydrogen fusion converts about 4 million tonnes of solar matter per second into electromagnetic energy, which is radiated into space.Potential energy is closely linked with forces.If the work done by a force on a body that moves from "A" to "B" does not depend on the path between these points, then the work of this force measured from "A" assigns a scalar value to every other point in space and defines a scalar potential field.
