Explain this common observation clearly: If you look out of the window of a fast moving train, the nearby trees, houses etc. seem to move rapidly in a direction opposite to the train's motion, but the distant objects (hills tops, the Moons, the stars etc) seem to be stationary . (In fact , since you are aware that you are moving , these distant objects seem to move with you. )

Text Solution

Verified by Experts

Near objects make greater angle than distant (far off) objects at the eye of the observer . When you are moving, the angular change is less for distant objects than nearer objects. So, these distant objects seem to move along with you, but the nearer objects in opposite direction.
