Given Newton's third law, why are things capable of moving?
Oct 29, 2016 · Newton's third law is traditionally taught as pairs of forces. I think it makes more sense to present it is as a single force that must always operate between pairs of bodies, as …
newtonian mechanics - Why does Newton's Third Law actually …
Jul 25, 2017 · If your question is "Why does Newton's 3rd law explain how rockets work?" instead of "Why does Newton's third law work?" then "conservation of momentum" works as …
Is Newton's third law always correct? - Physics Stack Exchange
May 29, 2014 · Newton's third law is not always correct, contrary to what you may have heard. It is correct in the context of newtonian mechanics, because we assume then that point particles …
Proof of Newton's Third Law - Physics Stack Exchange
Sep 7, 2021 · That "proof" is just circular reasoning hidden with a bad diagram. If you label the masses 1, 2, and 3, it shows that the force of 1 on 2 has to be the opposite of the force of 3 on …
Newton's Third Law and conservation of momentum
Oct 21, 2018 · As far as the actual physics is concerned, it is meaningless to talk of whether conservation of momentum is "more fundamental" than Newton's third law -- you can …

Why is normal force not the same as newtons third law
May 30, 2017 · And what is the force that cancels the counteracting gravitational force, would it not accelerate upwards because of the net force it has from the counteracting gravitational …
Is Newton's 3rd law of motion not applicable to gravitational force?
Nov 25, 2021 · Newton's 3rd law of motion states: When two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. Consider a scenario where …
