Question 10 • Physical Science

According to Newton’s third law of motion, which are equal?

Answer
A
momentum and velocity
B
mass and momentum
C
action force and reaction force
D
collision time and stop time

Explanation

Newton’s third law says that when one object exerts a force on another, the second object exerts an equal-magnitude force in the opposite direction on the first. Therefore, the action force and reaction force are equal. Collision time and stop time, mass and momentum, and momentum and velocity are not pairs that the law says are equal.
