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.
