Physics:Specific kinetic energy

Specific kinetic energy
Common symbols	ke, or ek
SI unit	J/kg, or m2/s2
Derivations from other quantities	ek = ½v2

Specific kinetic energy is the kinetic energy of an object per unit of mass.

It is defined as $\begin{array}{c}{e}_k=\frac{1}{2}\end{array}{v}^2$,

where $e_k$ is the specific kinetic energy and $v$ is velocity. Specific kinetic energy is an intensive property, whereas kinetic energy and mass are extensive properties. The SI unit for specific kinetic energy is the joule per kilogram (J/kg), which is equivalent to m²/s².
