The linear momentum (or simply momentum) $p$ of a body of mass $m$ is defined as

$p=m v$

where $v$ is its velocity. More generally, momentum is a vector, defined by

$\mathbf{p}=m \mathbf{v}$

Curiously, there is no named SI unit for measuring momentum. Momentum in SI units is measured in units of $\mathrm{kg} \mathrm{m} / \mathrm{s}$ .
