1. The problem statement, all variables and given/known data
Is it possible for a particle to describe a curved path if no force acts on it? Is the answer reference frame dependent?
[I am sorry. I forgot that the rule says on question per thread. ]
3. The attempt at a solution
YES, when the body stays still but the frame describes a curved path. Then with respect to that frame the body will describe curves but no force would act on particle. Will we count pseudo force as a force?

I guess it matters whether we are considering accelerated reference frames, or just strictly inertial reference frames.
Or put another way, do you think they are considering reference frames in which F=ma is not true?
