The product of a body's mass and its velocity.
Mass x Velocity.
increase momentum due to mass
Conservation of momentum
Adding the two momentums together eg, AFL; if one player is running at 30m/s and the opposing player is running at 20m/s the collision will equal a momentum of 50m/s.
Applying a force to an object over a given amount of time causes a change in momentum.
Impulse = force (N) x time of force application.
Increase in momentum due to increase in velocity
