Question

which of the following is an example of an action - reaction force pair? the force of a foot on a soccer ball and the force of the ball on the foot. the force of a bat on a ball and the force of the bat on the air. a person pushing a door and the door swinging open. the force of gravity on a ball and the balls motion toward the ground.

Explanation:

According to Newton's third - law, action - reaction force pairs act on two different objects and are equal in magnitude and opposite in direction. In the case of the foot on the soccer ball and the ball on the foot, the foot exerts a force on the ball (action) and the ball exerts an equal and opposite force on the foot (reaction). The other options do not meet the criteria of action - reaction force pairs. For example, the force of the bat on the air is not the reaction to the force of the bat on the ball. The door swinging open is a result of the applied force, not a reaction force in the Newton's third - law sense. The ball's motion due to gravity is not an action - reaction pair as it involves only the ball and the Earth's gravitational field in a non - paired force sense here.

Answer:

The force of a foot on a soccer ball and the force of the ball on the foot.
