Anyone know of an example of a violation of Newtons third law that occurs in everyday life?

Answer 1

Yes there are indeed violations of Newton's 3rd law.

I was reading the section in David Griffiths' electrodynamics book the other day about how Newton's 3rd law fails in relativistic dynamics (but somehow momentum conservation still works!)

He gives a simple example of two point charges converging, one traveling down the y-axis and the other coming in along the x-axis so they're headed for the origin. It turns out the magnetic forces each exerts on the other are not in opposite directions(!), so Newton's 3rd law is violated.

I'm not sure if this counts as "everyday life," though.

Shane S below isn't fully understanding my answer. It's when you do the explicit calculation of the forces the two particles feel that you find that they are not related the way Newton's 3rd law would predict. The 3rd law says the two forces should be equal in magnitude and exactly opposite in direction. They're not. Newton's 3rd law fails in this case.

Answer 2

There is a theory that there is a thermo dynamic way to violate the law will quote a little from the link that I am sending.

We are going to describe a rocket like vehicle system that can produce thrust without throwing off mass, even in a vacuum, by utilizing a thermal kinetic mechanism. This propulsion system proposes that there is a way to increase and decrease momentum thermally. That if you do these operations in separate chambers that are hot and cold respectively on the same gas sample, a momentum partial rectification process is realized. We do not think that Momentum is conserved as it is presently understood in this process but the process of producing thrust does takes energy and entropy does increase.

Answer 3

Not even in Steves scenario, because the forces playing on them would be calculated, so therefor Newtons laws still stand. However, newtonian physics don't hold up very well when you get into Quantum mechanics. But, anything you would notice on a day to day basis? No, Newtons laws hold firm.

Answer 4

If there were any such thing, I'd like to know about it too!

There are no known violations of Newton's 3rd Law. If there were, it create a sensation in physics, and would be front-page news.

Answer 5

Newton's 2nd regulation = You throw a pie at somebody, the extra advantageous you enhance up that pie, the extra advantageous the stress will consequence the objective. Newton's third regulation = a rocket, the rocket pushes gas on the floor and the floor pushes the rocket returned up.

Answer 6

There are no violations of Newton's third law.

Answer 7

the reason it is called a LAW is because it has been proven fundamentally and mathematically. so no i cannot
