Question

according to the equation, impulse is equal to ... the change in an objects momentum. the momentum of an object. an objects mass times its acceleration. the net force applied to an object.

Explanation:

Impulse - momentum theorem states that impulse ($J$) is equal to the change in momentum ($\Delta p$) of an object, i.e., $J=\Delta p$. Momentum of an object is $p = mv$, mass - times - acceleration is force ($F=ma$) and net force is just the overall force acting on an object.

Answer:

the change in an object's momentum.
