Because it is travelling forward the same speed as the train.

It depends on how hard you throw it and whether it is thrown in the direction the train is going or in the opposite direction.Thrown in the direction the train is moving and the object will move relative to the ground at the train speed plus the ball speed relative to the train. Thrown the other way at faster to the ground than the train it will proceed back the track at its ground speed minus the train's speed, At less than train speed the ball will follow the train.
We did this as kids by throwing a ball off the back of an old jalopy It was interesting to see the ball follow the car when thrown out the back.

Lets say that you are the something for this experiment.
There you sit on the train. The train is travelling at 70mph. Because of this, YOU are travelling at 70 mph. If you weren't, then you'd remain behind.
So, if you jumped in the air for that brief moment, your velocity is still pretty much in keeping with the train thanks to the energy pushing you forward still in effect.
If you hit a ball with a bat, that ball is in effect pushed by the energy of the bat's force. The same is happening to you on a train, but with less painful results.
If this effect didn't occur, just imagine what would happen if you jumped when on a plane. You'd slam into the back wall and turn into pizza.

because think about it... UK trains wont be going anywhere - wrong kinda leaves will be blocking the line.
If the train aint going anywhere, neither is the thing you throw in the air.
I think its because the object already has the perpetual motion of the train stored as its own potential energy, and so continues to move at the same speed even whilst airborne. Any additional energy applied will make the object move at the velocity of the train plus the speed gained by the force applied.

It will move the way the train is moving. It will go at the speed you throw it at plus the speed of the train.

Because it was going the same speed as the train was since it was on the train. If you threw it out of the train it might be a different story.

The same reason that if your in a lift an the cables break an it drops ten floors without stopping or slowing you cant just step off before impact an be saved. Its all relative.
Its the reason why they never made a military concorde, it flies faster than the speed of sound so if it ever opened up its guns it would shoot itself down!!!! LOL

Because every object on the train is going at the same speed!

because the air for the speed is on the outside if you throw it out side it will go of course
the same as a plane

that old chestnut called gravity, Sir Issac Newton invented it, before that apples used to float upwards, people on trains found it hard to walk forwards in a carrige due to the thrust of the trains momentum, and if you jumped in a lift you would hit your head on the ceiling.
Then along comes Issac and spoils it all for everyone.
