Question

1. what is the impulse - momentum theorem?

the impulse of an object is less than the change in its momentum.
the impulse on an object is equal to the change in its momentum.
the impulse of an object is inversely proportional to the change in its momentum.
the impulse of an object is greater than the change in its momentum.

Explanation:

The impulse-momentum theorem is a core principle in physics that directly states the impulse exerted on an object (the product of force and time applied) is exactly equivalent to the change in the object's momentum (mass times change in velocity).

Answer:

The impulse on an object is equal to the change in its momentum.
