Linear Momentum is the product of the mass and the velocity of a moving object.Its SI meassurment unit is 1 kilogram-meters per second (1 kg*m/s).

Like velocity, momentum is a vector quantity (it has a magnitude and a direction):

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

## Conservation of Momentum

The linear momentum of a close system that isn't affected by any external forces is conserved.

## Relation between Momentum and Force

$\vec{F} = m\vec{a}$

$\vec{a} = \frac{d\vec{u}}{dt}$

$\vec{F} = m\frac{d\vec{u}}{dt}$

$\vec{F} = \frac{d\vec{p}}{dt}$

Which means that the rate of change of the momentum of an object is proportional to the force F acting on it.
