What is impulse equal to in terms of momentum?

Explanation:
Impulse is the effect of a force acting on an object over a period of time on that object's motion. The amount of impulse equals the change in momentum: J = Δp = mΔv. This is the impulse–momentum relationship, so impulse measures how much the object's momentum changes due to the force. If the force is constant, impulse also equals FΔt, but the direct link to momentum is that it equals the change in momentum.
