What does E=mc² mean?


E=mc² explains how energy and mass are linked. E is the energy in an object, while m is the mass, c is the speed of light. The equation would show that energy equals the mass multiplied by the speed of light, and multiplied by the speed of light again.


It could work out the amount of energy that can be released by something. It could tell us the amount of energy released from an atom bomb. The energy that could be released is strong enough to destroy and entire city.
