  Hi,
  
  Interesting question. Actually, the ball doesn’t fly backwards. It is that the train is moving fast and the ball has the same inertia as the train when inside. If you let it drop from the window, the ball feels like it suddenly stooped and would drop down. Of course, if the train is moving fast, you’d have the impression that the ball went backwards because you are now moving much faster than the ball.
  
  If you drop it inside the train, the ball, you and the train have the same relative speed, so that is why it just stays there and it seems like it just dropped right in front of you.
