I used the word invalid because Laws 1 and 2 involve force, and the classical concept of force doesn't exist. And I can't say anything about Ehrenfest, because I don't know anything about it. I'm just an incoming first year student.ZapperZ said:Whoa! Go back a bit. Where exactly in QM are Newton's 1st and 2nd laws "totally invalid"? What do you think you get when you apply Ehrenfest theorem in QM?
Zz.

The "law of exceptions" is not a recognized law of physics. Posts about it will be deleted.Akshat said:according to the Law of Exceptions
Take two protons moving with velocities at right angles to each other. The magnetic forces exerted by each on the other do not follow Newton's third law.Akshat said:I've been noticing that there are exceptions to every scientific law.

Proton 1 (p1) moving in the positive x direction, currently at some position on the positive x-axis. Proton 2 (p2) moving in the positive y direction, currently at some position on the positive y-axis.Drakkith said:How so?
Newton's Third Law states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object will exert an equal force in the opposite direction.
No, Newton's Third Law is a fundamental law of physics and has been consistently observed and tested in various experiments. It is considered to be one of the most fundamental principles of classical mechanics.
There are no known exceptions to Newton's Third Law. However, there are situations where it may appear that the law is being violated, but this is due to other factors such as friction or external forces.
Yes, Newton's Third Law applies to all types of forces, including gravitational, electromagnetic, and nuclear forces. It is a universal law that governs the interactions between all objects in the universe.
Newton's Third Law has many practical applications in everyday life, such as in sports where the force of impact and reaction can be seen in actions like throwing a ball or hitting a baseball with a bat. It also applies to the movement of vehicles and objects, as well as the functioning of machines and tools.
