Newton's third law relates to a more fundamental principle, the conservation of momentum. The latter remains true even in cases where Newton's statement does not, for instance when force fields as well as material bodies carry momentum, and when momentum is defined properly, in quantum mechanics as well.
The strong form of Newton's third law requires that F and −F act along the line connecting A and B, while the weak form does not. Illustrations of the weak form of Newton's third law are often found for magnetic forces.

English: In this image, Newton's Laws of Motion are shown throughout common occurrences of a soccer match. In the first law, the ball is influenced by the wind, an unbalanced force, causing it to roll. In the second law, the ball is being kicked causing its acceleration to be dependent on the mass of the soccer ball and the net force of the kick.
Voltaire's Eléments de la philosophie de Newton (Elements of Newton's Philosophy) of 1738 was the first publication to use the terminology of "laws". [ 6 ] [ 7 ] The Biographical Encyclopedia of Astronomers in its article on Kepler (p. 620) states that the terminology of scientific laws for these discoveries was current at least from the time ...
By Newton's 3rd law if body A exerts a force on body B then B exerts an equal and opposite force on A. This should not be confused with the equal and opposite forces that are necessary to hold a body in equilibrium.) Internal forces. (For example, if an entire truss is being analyzed, the forces between the individual truss members are not ...
Third law may refer to: Newton's third law of motion, one of Newton's laws of motion; Third law of thermodynamics; Kepler's Third law of planetary motion;
One problem frequently observed by physics educators is that students tend to apply Newton's third law to pairs of 'equal and opposite' forces acting on the same object. [5] [6] [7] This is incorrect; the third law refers to forces on two different objects. In contrast, a book lying on a table is subject to a downward gravitational force ...
