Well, suppose we forget about the current term for a minute (we want to look at the field A on it's own, no currents around, to easily identify the mass.) Kinetische energie of bewegingsenergie is een vorm van energie, eigen aan een bewegend lichaam, vanwege de traagheid van massa. De kinetische energie van een bewegend lichaam is (relativistische referentiekaders uitgezonderd) recht evenredig met de massa van het lichaam, en met het kwadraat van zijn snelheid. De kinetische energie van een bewegend lichaam is bovendien gelijk aan de a…

If a body's speed is a significant fraction of the speed of light, it is necessary to use relativistic mechanics to calculate its kinetic energy. In special relativity theory, the expression for linear momentum is modified. With m being an object's rest mass, v and v its velocity and speed, and c the speed of light in vacuum, we use the expression for linear momentum , where .
