Momentum is mass times velocity Impulse is quantity force times time interval The greater impulse the greater change in momentum and vice versa To make the impulse greater than what it was before is by adding place were the impulse bounces around. Conservation of momentum is that with out and external force the momentum in the system will not change. Net Force before and after in a collision are the same. But in the elastic collision the momentum carries from one object to the next object it hits and they will have the same amount of velocity. Then there is inelastic collision is when an object hits another object, both objects end up with the same momentum unlike elastic were one lose it momentum to another object. Momentum Vectors is to show the momentum in direction but the two momentum after and before are the same amount.
