Answer:
A. momentum
Explanation:
"Momentum" by definition is found by the mass of the object x the velocity of the object. It also defines the speed you are going in, and how much faster or slower you are going.
For example, you need to find the momentum of a car, who's mass is 100 kg, and the velocity is 20 mph.
Momentum = 100 x 20
Momentum = 2000
