The change in momentum of an object is equal to the question 4 options: force acting on it times its velocity. impulse acting on it. change in velocity of the object.

impulse acting on it

Explanation:

The impulse is defined as the product between the force applied to an object (F) and the time interval during which the force is applied ():

We can prove that this is equal to the change in momentum of the object. In fact, change in momentum is given by:

where m is the mass and is the change in velocity. Multiplying and dividing by , we get

and since is equal to the acceleration, a, we have

And since the product (ma) is equal to the force, we have

which corresponds to the impulse.
