For identifying action reaction pair you would have to identify the two interacting objects and deciding who is pushing on whom and in what direction.

Here I would like to mention one more fact that is any pair of equal and opposite force is not an action reaction pair. Important thing to note about action -reaction forces is that they are two forces acting on two different bodies. Now we can state the Newton’s third law of motion in terms of action and reactionĪction and reaction are always equal and opposite. Any one of the forces in the pair can be called action force and the other force would be called as reaction force. Such a pair of forces, exerted by two bodies on each other, is called an action-reaction pair. These two forces have equal magnitude and have opposite direction. Whenever object A apply a force on object B, there is also a force applied by object B on object A. To understand this consider two objects A and B. If you hit the wall with your fist, the wall also hits your fist with the same force, which you feel.The force he exerts on the boat (action) is responsible for its motion and his motion to the shore is due to the force of reaction exerted by the boat on him. When a man jumps from a boat to the shore, the boat moves away from him.Where $F_$ is the force applied by the book on the hand. According to Newton’s Law, the book also exerts force on your hand and the magnitude of the force applied by book on your hand is equal to the magnitude of force applied on the book by your hand.

Now you push the book towards th eleft hand side by using your hand to apply force.

Consider a book being placed on a table as shown below in the figure.

Some of the examples of Newton’s third law of motion are This means that forces always occur in pairs. In any interaction between two bodies, force applied by the first body on the second is equal and opposite to the force applied by the second body on the first Now Newton’s third law of motion states that So here both he bodies are interacting with each other. You must have observed that when a body exerts a force on another body, other body also exerts force on the first body. Here in this article we shall discuss about the Newton’s Third Law of motion which is the relation between the forces themselves.
