Main Concept

The linear momentum of an object, denoted $\overrightarrow{p }$, is defined as the product of its mass $m$ and its velocity $\overrightarrow{v}$:

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

As a result, a massive object moving quickly has a greater linear momentum than a small object moving slowly.

Note that linear momentum is a vector quantity, as it is the product of a scalar (mass) with a vector (velocity).
