Impulse and Momentum

Question 10 • 2001310 Earth Science Sem 1 - Reeves

What best describes an impulse acting on an object?

Answer
A
the net force on an object divided by the time of impact
B
the velocity of an object divided by its mass
C
the product of an object's mass and the time of force impact
D
the product of an object's mass and its change in velocity

Explanation

Impulse equals the change in an object's momentum: J = Δp. Since momentum is mass times velocity, an object's impulse is its mass multiplied by its change in velocity, matching “the product of an object's mass and its change in velocity.”
