Momentum

The momentum of a mass $ m$ is usually defined by

$\displaystyle p = m v,
$

where $ v$ is the velocity of the mass. Note that momentum is a vector quantity in general, so we should more clearly write

$\displaystyle \underline{p}= m \underline{v},
$

where $ \underline{p}$ and $ \underline{v}$ are vectors in 3D space. We will return to vector momentum in §B.4.1 below.
