Ok people lets just assume this now....?

Question

earth rotates on its axis and goes around the sun in an orbit right? so we are on a ball spinning around and around and around.....




couldnt people just jump in the air while the earth is rotating below them and then some down because of gravity???
and then land in a different spot??????????


ive been wonderin for a time now

Answer 1

Think of it this way...
If you're on a train, and you are bouncing a ball off of the floor of said train...
The ball bounces right back up to you, right?
Now, in the same circumstance, someone is observing your actions outside of the very train you are bouncing your ball within...
They would not see the ball bouncing straight up and down, the way you would.
They would see a ball that bounced up and down along a series of arcs; as the train moved, so would you and the ball...
This is, essentially, Einstein's theory of 'Special Relativity', whereas the observer's point of view is important only to the observer.
Does that make sense?
Admittedly, it takes a while to wrap the head around an idea like this, but it;'s true...

Answer 2

Hey check this out...

Get into a bus traveling down the highway at 50 miles per hour. Slip out of your seat, and stand up...Now jump up in
the air...

Did you come down way back in the rear of the bus, or did
you come down right where you jumped up???

Well, the reason you came down where you jumped up is that
you were traveling along with the bus at the same rate of speed, just like when you are walking on the surface of the Earth. You and the surface of the Earth are moving together.

If you want to really get freaked out...check out the Moon.
The Moon is 240,000 miles away. look at it through a fixed
telescope at about 60X magnification or more. You cannot keep the Moon in view because it is moving so fast. My quick calculation shows the Moon is moving at about 2,272 Miles Per Hour around the Earth. Yet when you look at it with your naked eye, it is just sitting there.Llook at it again in 30 minutes and you will see that it has moved from where it was to a new spot in the sky.

Answer 3

No. Because we are moving with the Earth, when we jump up, it's as if the Earth is throwing us in the direction it's moving - we have initial momentum in that direction as well as up. Like when you jump up on a ship but come down in the same place - the ship is moving you forward, even if you didn't feel it (say, at a constant velocity).

Answer 4

No. Because you are still moving with the rotation of the earth. You don´t just stop in your track because you jump up. Also the atmopshere is also moving with the rotation of the earth. It sweeps you along as you jump up.
