Specific kinetic energy

Specific kinetic energy is the kinetic energy of an object per unit of mass.^[1]

It is defined as ${\displaystyle {\begin{matrix}e_{k}={\frac {1}{2}}\end{matrix}}v^{2}}$,

where ${\displaystyle e_{k}}$ is the specific kinetic energy and ${\displaystyle v}$ 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.
