# Momentum

## Standing Still?

When an object is not moving, always remember it has a momentum of

__ZERO____Example__

Momentum (kg m/s) = Mass (kg) x Velocity (m/s)

= 20000 Kg x 0 m/s

= 0 km m/s

## Momentum (kg m/s) = Mass (kg) x Velocity (m/s)

## Law of Conservation of Momentum

The law of conservation of momentum states that the total momentum of a closed system does not change.

The total momentum before an event is equal to the total momentum after an event.
