What will happen if you jump upwards in a forward moving train?

Question

Will you land back at the same point?

What if the train has both its ends open?

Answer 1

Yes, if you jump straight up inside a moving train, plane, bus or other closed vehicle moving at constant speed, you will theoretically land on exactly the same spot. Experimentally, you will land very close to the same spot; how close depends on how straight up you jumped and how well you can measure the take off and landing spot. Also, if you rotate your body or
stick out your arms your feet will land in a slightly different spot since it is your center of gravity that goes straight up and down.

This works because you are travelling just as fast as the train before, during, and after your jump. If the train accelerates (speeds up or slows down) while you are in the air, this is not true and you won't land in the same spot. Also, if you not in a closed cabin (for example standing on a train flat car), the wind will exert a force on you, you will slow down, and
not land on the same spot. Inside a closed train, the air inside the train is travelling at the same speed as the train and so will not exert a force on you.

You can most easily check this by throwing up a ball while you are in a moving vehicle and see if it comes straight down as it does when you are not travelling.

Answer 2

With the air enclosed, you would land in the same place.
If both ends of the train were open, there would be a huge flow of air through the train against which you'd have a hard job standing up.
If you jumped up, you would be blown heavily backwards due to the force of the wind acting on the area of your body..

Answer 3

Since you are at rest with respect to the train you and someone watching you would see you just go up and then back down. You're moving with the earth and works the same here. If both ends of the train were open, you'd probably get your hair messed up by the wind.

Answer 4

Unless the train accelerates, you will land on the same point on the train.

If the ends and/or windows are open, the apparent wind created by the trains motion might blow you back somewhat.

Answer 5

Unless the train either brakes hard or accelerates WHILE you are actually in the air, you will land on the same spot.

Answer 6

The ahead speed you've in basic terms formerly jumping (ie practice %) remains with you as you leap.. so in-actuality you proceed with the practice's % even as jointly transferring up/down contained in the air .. it truly is why you land decrease back interior a similar position. If the practice were to regulate % even as you've been jumping (now no longer in contact with the practice), you need to observe a replace in landing position .. if the practice slowed down you need to be transferring alongside swifter and land further ahead contained in the carriage, if the practice sped up you need to be 'left in the back of' even as contained in the air and land further decrease back.

Answer 7

you will land in the same spot because your horizontal velocity is the same as the train.

Answer 8

you land at the same point- you are travelling at the same speed as the train.
