What is Newton’s Third Law of Physics

Newton’s Third Law of Physics


Newton’s Third Law

For every action there is an equal and opposite reaction.




According to Newton’s Law of Motion, we have:


F (Action) = – F (Reaction



The negative (-) sign indicates that the two forces are parallel but in the opposite direction. If we consider one of the interacting objects as A and the other as B, Then a.


According to the Third Law of Motion:


F(AB) = -F(BA) E


F (A B) represents the force exerted on A and F (BA) is the force exerted on B.




  1. When we walk on the ground, we push the ground backward and as a reaction the ground pushes us forward. Due to this reason we are able to move on the ground.


  1. If a book is placed on the table, it exerts some force on the table, which is equal to the weight of the book. The table as a reaction pushes the book upward. This is the reason that the book is stationary on the table and it does not fall down.

This is much less than my usual volume of books read, but I have to devote enough time for it. To find him, I had to compromise – I watched less TV and stopped using social networks. Otherwise, I wouldn’t have had time to read. As a child, I could read up to a hundred books a month, but at that time I was not doing anything else – I only read all day. Unsplash Arithmetic has never been my strong subject, but let’s do some rough calculations.
