Kinetic Energy of Body at Constant Speed

Theorem

Let $B$ be a body of mass $m$ moving at a speed of $v$.

Let $v$ be considerably less than the speed of light.


Then the kinetic energy $T$ of $B$ is given by:

$T \approx \dfrac {m v^2} 2$


This article is complete as far as it goes, but it could do with expansion.
In particular: Add a subpage giving the relativistic KE of $B$
