<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> Why do the objects like trees, buildings, electric poles etc. appears to be moving in the opposite direction when you are sitting inside a moving train?

Answer 1

<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> When we observe nearby stationary objects such as trees, houses, etc. while sitting in a moving train, they appear to move rapidly in the opposite direction because the line of sight changes very rapidly. This is an optical that happens since the train is moving extremely fast.
