is it momentum

It's because you are moving at the same speed as the train and there is nothing to slow your momentum in the small time it takes to jump up and land.

It's called inertia. It's the same thing that makes a person fly out of a car during a crash. You are traveling at the same speed as the train, car, plane, etc. If you could jump high enough to stay in the air for an appreciable period of time you would eventually slow down as gravity became more of a factor.

Both you and the train have the same initial velocity.
Thank goodness it works this way. The Earth is moving too, spinning on its axis with respect to the Sun and other planets, and life would stink if we ended up several feet back or even splattered against a fence or building every time we jumped in the air.

Do you know, I actually tried that out. Same as throwing water into the air. It stays in the same place just as though the train was stationary.
On the other hand, I was downwind of a child who decided to throw up over the side of a cross channel ferry. The amazing thing was, I felt it hit (SPLUDGE!) and could smell it, but when I looked for it to wipe it off, there was nothing there. The speed of the boat (the wind) had blown it clean off! Amazing! And she was on the deck above, about 25 metres away.

It's like throwing something. After you release it, it does not stop in mid air and drop to the ground. Basically, when you jump, you are being thrown forward, just as a ball would be, but the train is moving at the same speed, so you land in about the same spot.

Momentum.

Technical term is inertia.
Your observation is not always true though.
If the train is just starting and accelerating, you would end up back.
On the other hand, if the train is stopping, and you jump, you would end up further.

you and the train are moving at the same speeds. although, with wind resistance, and all, there is a possibility that you will end up a little further back.

You are travelling at the same speed as the train,sat down stood up jumping in the air whatever, same speed....

!!!!!!!!!The air around the train is going fast and moving, not the stuff actually inside the train. Think about it.!!!!!!!!!!
