As a ball falls, the action force is the pull of Earth's mass on the ball. The reaction force is the
A)air resistance acting against the ball.
B)acceleration of the ball.
C)pull of the ball's mass on Earth.
D)nonexistent.
E)none of the above

Question

Quizplus · Accepted Answer

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, the action force is the gravitational force exerted by the Earth on the ball, and the reaction force is the gravitational force exerted by the ball on the Earth. Therefore, the correct answer is C, the pull of the ball's mass on Earth. Choices A, B, and D are all incorrect as they do not describe the reaction force in this scenario.

As a Ball Falls, the Action Force Is the Pull
