earth's rotation??

Question

well i always wondered this, why if the world is spinning like over 1000 mph, that when we jump the earth just dosent like spin, i mean when we jump why do we land in the same place?
always wondered this. i heard things about the atmosphere and gravity but still dont understand this

Thank You

Thank You

Answer 1

Newton's first law is the reason. It states that objects at rest remain at rest, and objects in motion remain in motion, unless acted upon by an external force.

So, while the surface of the Earth is moving at around 1000 mph, so is everything on the surface of the Earth. When you jump, you stay in the air for perhaps 1 second. During that 1 second, the ground under your feet has moved about 1500 feet, but you have also been traveling sideways at 1500 feet per second, and so has the atmosphere.

So, your relative velocity to the ground and to the atmosphere is zero. That's why you land in the same spot, and don't feel lots of sideways wind.

Answer 2

If you stand in a railway carriage which is travelling at 60 or 80 miles per hour, and jump into the air, you land on the carriage floor again at the same place as you jumped from. For exactly the same reasons, you land in the same place when you jump from the surface of the Earth.

Answer 3

Because we are held to the earth by gravity, so we are spinning with the planet at the same speed while we are on the ground. In theory, if we jump straight up, there is a slight difference in wheree we land, but that is so tiny as to be virtually unnoticable.

Answer 4

Hiya :)

It is because YOU are also travelling at 1000 mph too - so just like when you are in a car travelling at speed, you and the entire contents of the car are all moving at the same space - so if you toss a ball into the air, it doesn't move backwards at 70mph (or whatever the car is doing)

You, the air around us , the world and Mr.s Miggins Hedgehog are ALL moving at around 1000mph - as is the air you might jump up into for a moment -so unless something slows you down (or speeds you up) you are going to land in the same place again

Answer 5

When the earth rotates the atmosphere around it rotates with it too
As we are inside the atmosphere when we jump we land in the same place.But if some one who is not on Earth see the motion he'll see the path of the fall in a different way

Answer 6

Because you are moving along with the Earth.

If you were standing in the aisle of a moving bus and you jumped up, then you would land where you jumped from. The bus wouldn't move underneath you and leave you crashing towards the back of it. That's because you have the same speed as the bus and are moving with the same motion of it.

Answer 7

We land in the same place, because our speed or totation, is exactly the same of the earth on which we stand on.,.,, and the mass of both, the erath and the jumper, have not changed during that fraction of time,,,,, we carry the same amount of inertia...and that is why, the mass that have the same inertia, will always fall vertically....no matter how fat or slow, the velocity of rotation of that particular planet might be...

Answer 8

coz along with the earth, its atmosphere is also rotating at the same speed.. which means, when u jump, u also rotate in the same speed.

Answer 9

it's not just the earth that's rotating, the atmosphere surrounding it are rotating too!, and you are within the moving system!
