Understanding the Concepts

* Force: A push or pull that can change an object's motion.

* Momentum: A measure of an object's mass in motion (mass x velocity).

* Impulse: The change in momentum of an object.

The Key Equation

Impulse (change in momentum) = Force x Time

Calculation

* Force (F) = 3.0 Newtons

* Time (t) = 5.0 seconds

Impulse = (3.0 N) * (5.0 s) = 15.0 Ns

Answer

The change in momentum of the object is 15.0 Ns (Newton-seconds).
