Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.

Whenever two objects interact, they exert equal and opposite forces on each other.

Every action has an equal and opposite reaction. So, if you were to apply a force to a football of 50 Newtons, the ball would push back on your foot with a force of 50 Newtons.

In simple terms, Newton's Third law states that for every action, there will be an equal and opposite reaction. So whenever two forces interact, they will exert equal and opposite forces to each other. So if you exert a force to push the wall, even if the wall is not moving, it exerts an equal and opposite force to your force to stay in place.

Ans:

Newton's 3rd Law "Actions and reactions are equal but opposite in directions.

For Example

A book resting on a table applies a downward force equal to its weight on the table. According to the third law, the table applies an equal and opposite force to the book.

Newton's Third Law: Action & Reaction

His third law states that for every action (force) in nature there is an equal and opposite reaction. If object A exerts a force on object B, object B also exerts an equal and opposite force on object A.

Every action has an equal and opposite reaction.

For example if I push a box with a force of 30 Newtons to the left but it doesn't move, then the box must be pushing back the the same (equal) 30 Newtons of force to the right (opposite).

Newton's third law states that every action has an equal and opposite reaction which implies that when two objects interact, they exert and equal and opposite reaction on each other.

Hi Reginald,


Newton’s third law states that for every action there is an equal and opposite reaction. Here, action refers to a force. So if an object A exerts a force on object B then object B also exerts an equal but opposite force on object A.


A real life example is when someone throws a ball, they exert a force on the ball and therefore the ball also exerts a force on the person which is equal in size but opposite in direction. So the person also moves back a little . This can be seen clearly if the person is standing on an almost frictionless surface so they can’t stop their movement, for example on ice
