The impulse experienced by an object is equal to the net force acting on the object multiplied by the length of time the force acts (Δp = ΣFΔt). The same impulse can be caused by a large force acting for a short time, or a small force acting for a long time.

It is a vector quantity. Newton's second law can be rearranged to reveal that the net force on an object is equal to the rate of change of the object's momentum. The larger the net force experienced by an object, the more rapidly the object's momentum will change.

And, according to one form of Newton's second law, the net force on an object is equal to the rate of change of the object's momentum. As a consequence of these two laws, the total momentum of a system of interacting objects is conserved if there is no unbalanced force from outside the system.
