i simply can not understand how. if you were to stand on a train and jump, you would end up in the same place you were when you jumped. similarly, how do flies fly on a train??

Answer 1

Everything in the train is moving in the direction of the train as fast as the train is. Including you, and the air. Assume the train is moving at 45 km/h. If you jump, you move up, but you’re also moving forward at 45 km/h. You, the air inside the car, and the train are all moving forward at 45 km/h, so you will come back down in the same spot because that spot moved with you.
