because the air outside the car is not moving along with the train if you were on the moon, where there is no air, then if you through a ball out the top of your moon-train-car, it would drop right back into the car when you throw the ball out of the train on earth, the air outside is moving relative to the train (because the air is stationary with the earth and the train is moving reative to the earth) if the train is going 40 mph, then the ball experience a 40mph wind the opposite direction of train movement, as soon as it clears the protection of the train and gets into the outside air a 40mph wind will blow the ball backwards pretty sportily the other way to look at it, which is just as valid, is that the air holds the ball stationary with the earth and the train speeds off at 40mph

I BET YOU MEANT " THROW " & NOT THROUGH
( WHICH MEANS SOMETHING totally DIFFERENT )
DEPENDS ON THE INERTIA OF THE BALL , & THE TRAIN & ANY RESISTANCE
Laws of motion & relativity explain it all
( hopefully the person throwing is also moving on the train with same velocity & direction)
if the inertia of the ball & the train remains same in the same direction ( without the resistance of air etc ) then it is possible
if you throw it out you have changed the inertia
the ball & train are no longer in the same direction
same applies if you throw the ball in a different angle than the motion & direction of movement
all object have to be relaitivley still ( at the same velocity in same direction)

It doesn't change what it is doing. If you throw the ball up to the ceiling, it will come directly down again. If you throw it out the window, it will also go directly down, but you won't be there because the train you are on has moved forward. The ball isn't moving backwards, just down. It is you who is doing the moving.

Well, it's true. Here we are concerned with three things, namely, the train, the atmospheric air inside, its velocity/speed. When the train is in motion, the air inside the compartment is also in motion. Naturally you are also moving in the same speed with the train. So when a ball leaves your hand to the train roof, the ball also acquires the same velocity in conjunction with the air inside and your body position. When the ball returns back to you also, it travels in the same speed as of the train, air inside and your hand. Whereas it is not the case with outside air. When the train is moving forward, the air moving backward. The ball once contacts the atmospheric air, it again acquires the same velocity and tends to return to a backward position. I believe, your question has to be revised as the ball inside the compartment doesn't fall forwards or backward but exactly to your hand, why?

well thts coz u, the ball and the train are in same state of motion.
when u throw the ball out , the ball is in an atmosphere which is at a different state of motion
