Introduction

Sir Isaac Newton's laws of motion are fundamental principles in physics that describe the relationship between a body and the forces acting upon it. Among these laws, Newton's Third Law, also known as the Law of Action and Reaction, states that for every action, there is an equal and opposite reaction. This law is crucial in understanding various physical phenomena, from the motion of objects to the behavior of celestial bodies. In this article, we will delve into the concept of Newton's Third Law and examine which of the following scenarios is NOT an example of this law.

Newton's Third Law: A Brief Overview

Newton's Third Law is a fundamental concept in physics that describes the relationship between two objects interacting with each other. The law states that for every action, there is an equal and opposite reaction. This means that if object A exerts a force on object B, object B will exert an equal and opposite force on object A. This law is often represented by the equation:

F_A = -F_B

Where F_A is the force exerted by object A on object B, and F_B is the force exerted by object B on object A.

Examples of Newton's Third Law

There are numerous examples of Newton's Third Law in everyday life. Here are a few:

  • A ball hits the ground: When a ball hits the ground, the ground exerts an upward force on the ball, which is equal in magnitude to the downward force exerted by the ball on the ground. This is an example of Newton's Third Law in action.
  • A person pushes a wall: When a person pushes a wall, the wall exerts an equal and opposite force on the person. This is another example of Newton's Third Law.
  • A car accelerates: When a car accelerates, the wheels of the car exert a force on the ground, which is equal in magnitude to the force exerted by the ground on the wheels. This is an example of Newton's Third Law in action.

Which of the Following is NOT an Example of Newton's Third Law?

Now that we have discussed the concept of Newton's Third Law and provided examples of its application, let's examine the following scenarios:

  • A ball hits the ground, and the ground pushes up on it with the same force: This is an example of Newton's Third Law, as the ground exerts an upward force on the ball, which is equal in magnitude to the downward force exerted by the ball on the ground.
  • I punch the wall, and my fist receives the same force back: This is also an example of Newton's Third Law, as the wall exerts an equal and opposite force on my fist.
  • I pushed my brother, and then my brother pushed me back: This is another example of Newton's Third Law, as my brother exerts an equal and opposite force on me.

However, the following scenario is NOT an example of Newton's Third Law:

  • A person is standing still, and there is no force acting on them: In this scenario, there is no action-reaction force pair, as the person is not exerting any force on their surroundings, and there is no force acting on them.

Conclusion

In conclusion, Newton's Third Law is a fundamental concept in physics that describes the relationship between two objects interacting with each other. The law states that for every action, there is an equal and opposite reaction. We have discussed the concept of Newton's Third Law and provided examples of its application in various scenarios. By understanding Newton's Third Law, we can better comprehend the behavior of objects in the physical world.

Q: What is Newton's Third Law?

A: Newton's Third Law is a fundamental concept in physics that describes the relationship between two objects interacting with each other. The law states that for every action, there is an equal and opposite reaction.

Q: What is the equation for Newton's Third Law?

A: The equation for Newton's Third Law is:

F_A = -F_B

Where F_A is the force exerted by object A on object B, and F_B is the force exerted by object B on object A.

Q: What are some examples of Newton's Third Law?

A: There are numerous examples of Newton's Third Law in everyday life. Here are a few:

  • A ball hits the ground: When a ball hits the ground, the ground exerts an upward force on the ball, which is equal in magnitude to the downward force exerted by the ball on the ground.
  • A person pushes a wall: When a person pushes a wall, the wall exerts an equal and opposite force on the person.
  • A car accelerates: When a car accelerates, the wheels of the car exert a force on the ground, which is equal in magnitude to the force exerted by the ground on the wheels.

Q: What is the difference between action and reaction forces?

A: Action and reaction forces are two forces that are equal in magnitude and opposite in direction. They are always present when two objects interact with each other.

Q: Can you provide an example of a situation where there is no action-reaction force pair?
