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 (hill tops, the Moon, 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).
When a person is sitting in a moving train, the object close to the train appears to move very fast because the line of sight for the object closer to the train is very small and therefore, they move very fast. On the other hand, objects like trees that are very far away appear to move slowly because of the large line of sight for the farther objects. Therefore, the closer house appears to move fast whereas the trees at a larger distance appear to move slowly in the backward direction.
