It is something that an object needs to do work. The standard unit of energy is the Joule (J) which is defined as the energy exerted on an object by a force of one Newton over a distance of one metre. The first law of Thermodynamics states that energy cannot be created nor destroyed and is instead transformed from one form to another[1]. Energy can be caluclated through the equation E= mc2 where m is the mass of an object and c the speed of light within a vacuum.
