Question

How does Newton’s third law apply to soccer?

Answer 1

We need to understand what Newton's laws of motion is all about to understand how it can be used in practical situations. The applications of Newton’s laws are very important in all the mechanical problems which are macroscopic in nature.

Complete Solution:
We know that the Newton’s laws of motion are the governing laws which determine the nature of the motion of a body under a given force. The three laws are important by themselves and are an unavoidable part of the physical world.

The first law of motion deals with the inertia of a body under rest or in a uniform motion. The second law defines acceleration as a by-product of a force acting on a body with a mass or the rate of change of impact or momentum on a body. The third law or the action-reaction law is famous for its application in everything around us. Every action has an equal and opposite reaction.

Now, let us consider the game of soccer. We know that a ball is used which can be moved only using the body parts other than the hand. We know that each striker or defender or any player in the game touches the ball and the ball changes its direction and speed according. Also, the ball hits the player with a reasonable force. This force can be called as the action. When this force hits a player’s leg an equal opposing force is applied by the leg which can stop the motion of the ball. This is called the reaction. Any force greater than the action-reaction pair will result in the further motion of the ball. Thus, Newton's third law of motion is useful in the soccer game.

This is the required solution.

Note:
The soccer game uses all the other two laws of motion also for a better play. We can see that the direction and magnitude of the motion of the ball which is to be constant is changed by the players resulting in goals and defends which is from the first law.
