Linear momentum, denoted $\vec{p}$, is a vector quantity defined as the product of an object's mass $m$ and its velocity $\vec{v}$:

The magnitude of linear momentum, $p$, depends on the mass and the speed $v$:

$$p = m \cdot v$$

The magnitude of an object's linear momentum tells us how hard it is to stop its motion. A heavier object will have more momentum than a lighter one if they have the same speed, and a faster object will have more momentum than a slower one if they have the same mass.
