What does impulse equal according to the impulse momentum theory?

According to the impulse-momentum theory, impulse equals the change in momentum of an object. Mathematically, impulse is defined as the product of the average force applied to an object and the time duration over which the force is applied. This relationship can be expressed as ( \text{Impulse} = F_{\text{avg}} \Delta t = \Delta p ), where ( \Delta p ) is the change in momentum. Thus, impulse serves as a means to quantify the effect of a force acting over time on an object's motion.
