Answer:
This equation helps to understand
The speed of light, c is constant in all reference frames and is roughly equal to 3.00x108 meters per second. In the context of Einstein's relativity, the c2 functions more as a unit conversion factor than a constant. As such, it is squared as a result of dimensional analysis - energy is measured in joules, or kg m2 s-2, so adding the c2 ensures that the relationship between energy and mass is dimensionally consistent.
Energy can be neither created nor destroyed, it can only take a different form. For example, coal has a lot of potential energy that turns into thermal energy when it is burned.
