If you jump up when inside a moving train how come you land in the same place?

Question

If you jump up when inside a moving train how come you land in the same place?

Answer 1

Because your body is travelling at the same velocity as the train.

Answer 2

Of course you mean same place in relation to the train... In fact you don't, you land slightly behind where you jumped from, assuming you jumped vertically.

Answer 3

you land on the same spot in the train but in reality you land on a different spot as the train is moving

Answer 4

Your Inertia is the same as the train. You are both moving. However if you jump from the outside of a moving train and are able to get in the air inside the train it would move under you.

Answer 5

You're travelling at the same speed as the train.  Why do you land in the same place when you jump in your yard, after all the earth is moving faster than the train?

Answer 6

hmmm - i dont know but i will have to try next time the train is empty. i have always wanted to know if you can jump in a fast falling lift???

Answer 7

You will land ever so slightly off from the point where you jumped, but in basically the same place.  It's because you're being carried along with the same momentum as the train, and you won't be in the air long enough for the train to move away from you.

Answer 8

you don't.

Answer 9

Never was too hot on physics, any scientists can correct the subtext of my answer later on.

If the train you are travelling on is moving at 60 mph, i.e. a mile a minute, then everything being pulled by the locomotive will move at the same speed. Although you don`t realise it, even when you are sitting on a seat on the train, there are forces at work dragging you along at 60 mph. Therfore when you jump up, you are jumping up at 60 mph, but everything inside the train is also moving at 60 mph, therefore you land back in the same spot, inside the train! However, assuming that you were airborne for 2 seconds, the train will have moved forward by 1/30th of a mile in those 2 seconds and so will you, so you aren`t actually landing in the same place as the spot you took of from.

Answer 10

because you're moving with the train.  everything inside the train is moving at the same speed, even the air inside it.

Answer 11

You don't . The second your feet leave the floor you begin to decelerate. Which would ever so slightly be just behind where you started. You will also feel slightly of balanced. When you land,  since your body will accelerate the second your feet touch the floor.

Answer 12

yes u do because as the train moves your body is moving at the same speed as the train is, as a result when u jump inside a train u are already moving at the same time at the same speed so u do not fall

Answer 13

Mate of mine jumped in front of a train cos he owed too much money on credit cards and landed up in hospital - he was lucky that time though.

Answer 14

Inertia. You are also moving - at the same speed as the train.

Answer 15

Try jumping down on a stationary train

Answer 16

conservation of momentum

Answer 17

this is like a fly that gets into your car when you are driving 60 miles per hour...the fly can fly around inside your car but it is not flying at 60 mph in doing so

Answer 18

Technically, you don't. You are moving at the same velocity as the train, so your position inside the train remains the same.

However, in the larger picture, you have moved in relation to the external world.

Answer 19

Inertia will cause you to travel the same speed as the train.  You will come down in the same place on the train, but not on the earth.

Answer 20

Inertia, doofus.

you and the train are both moving forward together. Then you jump and you are still moving forward (though in the air), while the train is moving forward around you and under your feet. Then you land.

If you could jump high enough, you wouldn't land in the same place, but rather a little farther back b/c you don't move exactly as fast as the train when you are in the air. (The train is continually getting energy to move forward, but you would be losing energy in the air.)

Answer 21

Because your moving with the train....Like Newton's law..."An object in motion tends to stay in motion"

Answer 22

You are moving the same speed as the train, and there's no resistance to keep you from moving forward.  It's similar to the idea of jumping up on an elevator -- you're still going down...

Answer 23

Because you are moving forwards at the same speed as the train as you start to jump.

If the train accelerates or decelerates, obviously you will land in a different place, except that the air in the train is being dragged along with it and is in turn exerting forces on you.

Answer 24

the trains forward motion is still active on you when you jump so you appear to move with it.

If you could jump high enouth to slow down then you would land on a different point.
