The discussion revolves around the applicability of Newton's laws in non-inertial frames of reference. Participants explore whether and how these laws are affected when considering accelerated frames, with a focus on the introduction of fictitious forces and the implications for the laws' validity.
Participants express differing views on the nature of Newton's laws in non-inertial frames, with no consensus reached on whether the laws fail or simply require careful application with the introduction of fictitious forces.
Participants highlight the complexity introduced by fictitious forces and the need to consider the system's external forces when analyzing non-inertial frames. There are unresolved aspects regarding the implications for Newton's third law.
raknath said:Why do we actually say that Newton's laws do not hold for non inertial frames. can you folks give me an example of how Newton's laws collapse in an non inertial frame(if they do at all)
And the fictitious forces do not obey Newton's 3rd law, so in patching the 1st and 2nd laws that way the 3rd law doesn't work any more.A.T. said:In accelerated frames objects with no forces acting on them accelerate. So you have to introduce "http://en.wikipedia.org/wiki/Fictitious_force" " to make Newtons laws work again.
