Question

What is the third law of motion?

Answer 1

If you press against a corner of this textbook with your fingertip, the book pushes back and makes a small dent in your skin. If you push harder, the book does the same and the dent in your skin is a little larger. This simple experiment illustrates a general principle of critical importance known as Newton’s third law:

If two objects interact, the force F12 exerted by object 1 on object 2 is equal in magnitude and opposite in direction to the force F21 exerted by object 2 on object 1:

Answer 2

Newton’s Third Law of Motion states that

For every action there’s an equal and opposite reaction

A funny example to remember this is that

Just imagine

When u slap ur friend

Ur friend slaps u again with the same force

So that’s an opposite reaction

Of course if there’s a close friendship then he may slap with a greater force too but don’t think in that way.....ok

So

For every action there’s an equal and opposite reaction
