Weak and strong laws of action and reaction

[Kodzikas]

What is the difference between weak and strong laws of action and reaction?
Can you give any examples?

[swansont]

There are two versions of action/reaction?

[Mordred]

Yes, though it's been years since I last heard those terms used.

 

 

Newton's third law is also known as the weak law of action and reaction. It states that for every action force, there is a corresponding reaction force which is equal in magnitude and opposite in direction.

For every action force, there is a corresponding reaction force which is equal in magnitude and opposite in direction. Furthermore, the forces are central forces, i.e., they act along the line joining the particles

Weak law is linear momentum

 

Strong law is angular momentum.

 

the difference is shown here.

The strong law involves the central force.

Here is a decent coverage on both.

Thank you. It makes sense now.

Thank you. It makes sense now.

No problem +1 for asking such a little known question.
