____

it depends on persons reference point as we know that motion and rest are relative terms ,  when we are sitting inside the train we are at the rest for the compartment members but when we take trees or the person as the reference point we will seem to be in the motion but when we will take ourselves as the refernce point the trees and the person outside will seem to be in the motion so it shows some object maybe at rest with repect to one reference  point and in motion with respect to one reference point
