Momentum is a
vector quantity. This means it has both
magnitude (how much momentum) and
direction (in which direction the momentum is pointing).
In physics, momentum is defined as the product of an object's mass and its velocity:
\[
\text{Momentum} = \text{Mass} \times \text{Velocity}
\]
Since velocity is a vector (it has both magnitude and direction), momentum also carries both these properties.
