What describes impulse in terms of momentum?

Impulse is fundamentally defined as the change in momentum of an object. In physics, momentum is the product of an object's mass and velocity. When an external force acts on an object over a specified time interval, the impulse experienced by that object causes a change in its momentum. This relationship is captured by the impulse-momentum theorem, which states that when a force is applied to an object, the impulse imparted by that force results in a change in the object’s momentum.

In practical terms, if a force is applied to an object, the greater the force and the longer it acts, the greater the change in the momentum of that object. Therefore, recognizing impulse as the change in momentum directly links the concept of how forces interact with moving objects and provides valuable insight into the dynamics of motion.
