How are momentum and impulse related? impulse is a whim to do something, while momentum keeps it going impulse is another name fore instantaneous momentum the impulse acting on and object is equal to the change of momentum it causes. the impulse that acts on and object is the momentum that results.

momentum of object is defined as the product of mass and velocity of the object.

so we have

While impulse is the change in momentum of object

so we can say

so here we have correct answer as

The impulse acting on and object is equal to the change of momentum it causes.
