Give a example physics is not acceptable?

Answer 1

heya!
here's your answer

so.. first of all.. before knowing anything else
let's know what physics actually is..

PHYSICS: physics is basically the study of how things function around us ..and their working and capabilities.like.. the solar system, certain machines etc.
it also includes measurements and calculations of certain quantities..like mass , weight, velocity etc.

Answer 2

If you are a high school student, I'd say Newton's laws do not work in non-inertial reference frames, where objects start to move without any physical force (this is already general relativity, if you want). Of course, if you are curious about quantum mechanics, you should go for a book, I would say. The short answer could be: in quantum mechanics, there is nothing called point-mass, particle or rigid-body etc.; so Newton's laws are talking about non-existant objects.
