Question

Newtons Third Law of Motion states that for every action there is an equal and opposite reaction. Which of these illustrates Newton's Third Law?
Choose one option
A
Two students of similar mass run into each other. They bounce off each other when they collide.

B
Two students of similar mass run side by side into a wall and punch holes of equal size before emerging on the other side.

C
Two students of similar mass run in opposite directions, but one accelerates at twice the rate of the other.

D
Two students of similar mass run at the same speed in opposite directions on a track. They will collide with 400 Newtons of force in 400 meters.

Answer 1

A

When the students collide they exert forces on each other that are equal in magnitude and opposite in direction, so they bounce apart — this is Newton's Third Law.
