Momentum

What is Momentum?

Momentum is a vector quantity and describes the motion of a moving object. Momentum is an indication of how hard it would be to stop an object.

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.
