1. How are impulse and momentum related?
(Points : 1)
Impulse is the change in momentum of an object.

Momentum is the change in impulse acting on an object.

Impulse and momentum are always equal in magnitude.

Impulse and momentum are the same thing.

Question 2. 2. Which of these is a statement of the impulse-momentum theorem?
(Points : 1)
F = ma

The impulse is the average force times the time of interaction.

The average force times the time of interaction equals the change in momentum.

Impulse has units of momentum.

Question 3. 3. Which of the following is the equation for impulse?
(Points : 1)
impulse = ma

impulse = mv

impulse = Ft

impulse = p
