It is correct to say that impulse is equal to

Impulse is equal to the change in momentum

Explanation:

The impulse exerted on an object is given by:

where

F is the force exerted on the object

is the duration of the collision

We can re-write the force F by using Newton's second law, F = ma:

where m is the mass of the object and a its acceleration. Now we can rewrite the acceleration as ratio between the change in velocity and the time elapsed:

and the product is the change in momentum of the object.
