2. How does the diagram illustrate Newton's third law of motion? In your answer, compare the force of the foot kicking the soccer ball with the force of the soccer ball on the foot.

Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. The diagram illustrating a foot kicking a soccer ball effectively demonstrates this principle by showing the interaction between the two objects—the foot and the ball. When the foot **kicks** the soccer ball, it **applies a force** to the ball in a specific direction (action force). Simultaneously, the soccer ball **exerts an equal and opposite force** back on the foot (reaction force). These two forces are: - **Equal in Magnitude:** The strength of the force the foot applies to the ball is exactly the same as the force the ball applies back to the foot. - **Opposite in Direction:** While the foot pushes the ball forward, the ball pushes the foot backward with the same intensity. Importantly, these forces act on **different objects**—the foot and the ball—ensuring they do not cancel each other out. This mutual interaction exemplifies Newton's Third Law by showing that forces always come in pairs, maintaining balance and allowing for the transfer of energy and motion between interacting bodies. For example, when a soccer player kicks the ball, the force exerted by the foot propels the ball toward the goal, while the reaction force from the ball slightly pushes the player's foot backward. This reciprocal action allows the ball to move and demonstrates the fundamental principle that forces always occur in action-reaction pairs.
