Solution
The correct answer is: Linear momentum is the product of mass and velocity. Impulse is the change in linear momentum.
Here's why:
-
Linear momentum (often simply called momentum) is defined as the product of an object's mass and its velocity. In other words, momentum = mass x velocity. This is a vector quantity, meaning it has both magnitude (size) and direction.
-
Impulse, on the other hand, is defined as the change in an object's momentum. It's calculated as the product of the force applied to the object and the time over which that force is applied. So, Impulse = Force x Time. This results in a change in the object's velocity, and therefore, a change in its momentum.
So, the key difference between the two is that momentum is a measure of how hard it would be to stop a moving object (the product of its mass and velocity), while impulse is a measure of how much the momentum of that object changes when a force is applied over a period of time.

The equation below shows the mathematical representation of the external impulse acting on a system, which is a vector quantity—resulting in (and equal to) the change in the system's linear momentum—caused by a net external force exerted over a time interval. Match each term in the equation with the correct description from this list: (1) Change in Time; (2) Net Sum; (3) External Force; (4) Change in Linear Momentum; (5) Impulse
