Theoreticaly,an object is floating in the air, would it be across the globe in 12 hours?

Question

due to the earth's rotation

Answer 1

How is your object suspended?
What you are really asking is this: Can an object maintain its position relative to the earth as the earth revolves for one half a revolution. The answer to this question is yes, providing it is holding a geosynchronous orbit in space.

NO---If it is floating and at the mercy of the wind then it could move in any direction the answer would be no.

YES--If your object is tethered to a post and flies a few feet away then the earth’s rotation will pull it around so that it will travel the same distance as the earth would travel in 12 hours.

NO---If you are suspending the object in orbit and in space then it will follow the orbital path and it will move faster than the speed of the earth’s rotation so it can maintain that orbit there fore it will move farther than it would if fixed to the earth.

YES--If you are suspending the object in a geosynchronous orbit deep in outer space then it would share the orbital paths of the GPS satellites and it would move in an orbit where the orbit speed matches the speed of the earth. Any objects in this kind of orbit will effectively remain stationary over the surface of the earth as long as it holds the orbit. Due to the speed that an object needs to move to match the rotational speed of the earth the orbit is a distant one, farther out than the Space Station, and farther out than the Hubble Space Telescope. Out where the communication satellites can be found.

UNKNOWN--If you are using an antigravity system to suspend the floating object then I can’t answer your question. If the antigravity field acts by matching the gravitational attraction of the earth then it could travel as fast as the earth does and there by remain over the same spot after 12 hours. Assuming of course that it was able to resist the wind somehow. If the antigravity field merely cancels out the gravity of the earth then it will be free to float in space. As the earth turns, the object will be immune (if you cancel out the power of the wind). However, as the earth revolves around the sun then the position of the object will change, it will either be closer or further from the earth. As the sun orbits in the Milky Way Galaxy and as our Galaxy travels through space more movement will be added to the equation.

Answer 2

no it also has the earths rotational velocity as part of its motion. While there is some drag in the atmosphere that are the cause of jetstream winds, objects on the ground do not move relative to the ground, nor do aircraft in the lower atmosphere.

Now an absolutly stationary satillite is a different story. To be stationary and in orbit I believe you must have reached escape velocity and be traveling a direct radial outward from the center of the earth. In that case, your shadow would indeed cross the globe every 12 hours

Answer 3

Nope.

Two things work against that, one is that the air moves with the earth. If that was not true, there would be a continuous 1000 mph wind blowing toward the west. The other thing that works against that is that if the object took off from earth, it had an initial speed equal to the speed of the surface of the earth, and it would have to be accelerated from 1000 mph to 0 to stop moving relative to the earth's surface.

So if you are planning to take a helicopter straight up and then wait for 12 hours to get to Europe, that won't work.

Answer 4

I don't think so. When I was a kid I thought if I jumped up and down for 24 hours (being in the air for half of that time) that I should be able to get half-way around the world in a day. I hopped for about 30 minutes and was still in the same spot, so I gave up. Sounded like a great idea at the time.

Answer 5

If you are saying that it would maintain the same point in relation to the sun, in 12 hours the earth would have made a half of a rotation.

Answer 6

No, that's no longer achieveable via fact of inertia. attempt leaping up on a rapid moing airplane, practice or bus. Do you notice your self shifting forward or backward? No, via fact you're already shifting on the comparable appropriate speed the airplane, practice, or bus is shifting. If this weren't genuine, in case you jumped in a airplane shifting 4 hundred mph you will desire to fly in the direction of the decrease back of the airplane like a bullet and specific die, yet that on no account happens. fairly, in case you have been to stay floating above the earth yet nonetheless in the ambience, you will possibly stay above the comparable usa, via fact you're stilling shifting on the comparable speed via fact the earth's rotation. the reason it would not sense like your shifting is brooding about's relative to the earth, and if each little thing else is shifting interior the comparable speed and course then it appears like no longer something is shifting.

Answer 7

well, first of all the object would not stay in the same place due to the law of orbits. anything that appears to be "floating" is actually falling constantly that is what an orbit is. and it would depend how far up the object is to find out how long the orbit takes.

Answer 8

It really depends on how fast it was going when it was launched into the air, what the wind speed was at the time, and what storm systems or cloud cover was present. Inclement weather would probably make that a big no no

Answer 9

Nope, the air rotates with the planet, and so does the object.

Answer 10

Depends on its hieght above the Earth, its weight, and what speed it's traveling at.
