What does impulse define in terms of momentum?

Impulse is defined as the change in momentum of an object when a force is applied over a specific time interval. Mathematically, impulse can be expressed as the product of the average force applied to an object and the time duration during which the force acts. According to the impulse-momentum theorem, the impulse experienced by an object is equal to the change in its momentum.

Momentum itself is the product of an object's mass and its velocity. Therefore, when a force is applied to an object, causing it to change speed or direction, its momentum changes. Impulse quantifies this effect, showing how much momentum is transferred or altered.

In summary, when discussing impulse in the context of momentum, it is the measure of the change in an object's momentum due to the application of a force over time.
