I don't quite understand Actions and Reactions. [For every action, there is an opposite and equal reaction.]Can someone let me know if I am correct on this question or not?

Identify the action and reaction forces in the following situations:

1. You kick a soccer ball and the soccer ball exerts an equal but opposite force on your foot. Ans- The action force is the kick on the soccer ball; the reaction force is the soccer ball kicking up on your foot.
2. You sit on a chair and the chair pushes up on you with an equal force. Ans- The action force is your weight on the chair; the reaction force is the chair pushing up on you
Thanks!

Those answers are correct. You appear to understand the action/reaction concept quite well.

what is action force

You are correct in identifying the action and reaction forces in both situations.

In the first situation, when you kick a soccer ball, the action force is the kick applied to the soccer ball. The reaction force is the soccer ball exerting an equal but opposite force on your foot. This is known as Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.

In the second situation, when you sit on a chair, the action force is your weight applied to the chair. The reaction force is the chair pushing up on you with an equal force. This reaction force helps support your weight and keep you seated.

To identify action and reaction forces in any given situation, it helps to consider the forces being applied by different objects or bodies involved. Remember that the action force and the reaction force always act on different objects and are equal in magnitude but opposite in direction.
