Question

newton third law kya hai?

Answer 1

Heya your answer is as follows :
____________________________________________________________________________________________________________
Newton's third law states that every action is equal and opposite to it's reaction .

It our common experience that whenever an object A exerts some pressure on another object B, the object B also exerts some pressure on object A . Experimentally, it is observed that these two forces are equal in magnitude but opposite in direction. If we call the force exerted by object A on object B as the action force. Then the force exerted by object B on object is called the reaction force. To make the concept clear be considered following examples:

• In the game of Hockey and football sometimes one player collides with another player. Both players feel hurt because each player applies force to the other player. Here force applied by one player on the object other is action force and the force exerted by second player on the first is the reaction force and both action and reaction forces are acting simultaneously.

• When you strike a rubber ball against hardball or hard floor the ball exerts a force on the wall or on the floor. This is the action force. In turn the wall or floor exerts and equal force on the ball in opposite direction due to this force of reaction the ball rebounds back to you. Newton's third law of motion tells us the relation between action and reaction forces .

In other words , the third law of motion states that when an object exerts a force on another object II object instantaneously exerts a force back on the first these two forces are always equal in magnitude but opposite in direction .

Hey mate!

Thank you for asking this question! ❤

_______________________________________________________

» The Newton's third law of motion states that, to every action, there is an equal and opposite reaction.

» When an object exerts a force on another object, the second object instantaneously exerts a force back on the first. These two forces are always equal in magnitude but are opposite in direction.

» The force exerted by an object A on object be is called the action force and the force now, exerted by object B on object A is called the reaction force.

♦ Some examples of Newton's Third Law of Motion ⇓

1. A ball rebounds after striking the hard floor

⇒ Here in this example, when the ball is thrown from a height, it strikes a hard floor, and therefore exerts a force on the floor. In return, the floor also exerts an equal and opposite reaction force on the ball making it rebound.

2. Flight of a bird

⇒ In this example, the bird, when it flies, pushes the air backwards with it's wings. In turn, the air also exerts an equal and opposite reaction force on the bird and therefore, the bird flies in the forward direction.
