When Arti kicks a football, two forces interact. Arti's foot exerts a force of 5N on the ball. What size force will be exerted on Arti's foot?

Break Down the Problem

1. Identify the forces involved in the interaction between Arti's foot and the football.
2. Apply Newton's Third Law of Motion which states that for every action, there is an equal and opposite reaction.

Relevant Concepts

1. Newton's Third Law of Motion: This law states that forces always come in pairs; when one object exerts a force on another, the second object exerts a force of equal magnitude but in the opposite direction on the first object.

Analysis and Detail

1. When Arti kicks the football, his foot exerts a force of 5 N on the ball.
2. According to Newton's Third Law, the football exerts a force back on Arti's foot that is equal in magnitude.
3. Therefore, if the ball receives a force of 5 N, Arti's foot also experiences a force of 5 N in the opposite direction.

Verify and Summarize

1. The interaction clearly follows Newton's Third Law; hence, the calculation is straightforward.
2. Both forces are equal in size (5 N), acting in opposite directions.

Final Answer

The size of the force exerted on Arti's foot is 5 N.
