Why does a person fall when he jumps out from a moving train in physics?
When the person was inside the train his body was also moving forward. While jumping out, his feet touches ground comes to rest immediately. But the upper part of the body still remains in motion due to inertia of motion and so he falls.

When moving with the train, the speed of the train is your speed. You are in the same frame of inertia. When you jump in the train, you do not encounter air resistance, and you usually encounter little to no force and there is no change in your speed. That's why you fall in the same place when you jump.
This is due to inertia. When the speeding bus stops suddenly, lower part of the body comes to rest while the upper part of the body tends to maintain uniform motion. Hence, the passenger's are thrown forward.
A getting passenger getting down from a moving bus, falls in the direction of the motion of the bus. This is because his feet come to rest on touching the ground and the remaining body continues to move due to inertia of motion.
If everyone on the plane jumped at the same time the plane would dip slightly and then return to normal flight. When everyone is mid-jump their weight will be momentarily removed from the plane. So the plane would actually be carrying less weight for that fraction of a second and its lift would continue to be the same.
When a bus stops suddenly, its passengers tend to fall forward because due to their inertia the passengers tend to remain in a state of motion even though the bus has come to rest.
Trespassing on the railway is illegal and dangerous. You could be taken to court and face a £1,000 fine. For this reason, when we see someone trespassing, we have to stop all trains in the vicinity to remove trespassers, check for damage and clear blockages.
