Speeding or Slowing?

[TimbaLanD]

When we are flying, are we speeding or slowing relative to the speed of rotation of the earth?

[YT2095]

that entirely depends on the direction you`re traveling in.

[TimbaLanD]

So you are saying if we go from west to east, we will speed up and slow down if we travel from east to west?

[YT2095]

basically yes.

 

if we consider an extension to this, think of a geostationary satellite, it`s traveling in the same direction as the Earths rotation at a same rate, Obviously at a greater velocity though because it`s higher up and needs to cover more distance as the circumference is larger.

[TimbaLanD]

Are you saying that if we fly from east to west, we actually have to slow down to reach our destination?

[YT2095]

relative to earths rotation yes.

 

of course we cannot Possibly hope to Match the speed that the earths rotates at, and effectively "Stay still" and let the destination come to You.

That would never happen (you`d burn up).

Superman did in his first film - in fact he went so fast that the world span bacwards and so did time!

I disagree. The equatorial speed is ~1000 mph, but goes down with latitude. At 50 degrees that drops below 650 mph.

So, what is our speed relative to someone standing in space watching me or you? it’s the same speed as the earths rotation, right? This is true for someone standing on the surface of the planet. When airborne are we still going in the speed the same speed as the planets rotation, right? Else we can go around the world in 24hrs??

 

My original question is that do we slow down or speed up when we are airborne relative to the speed of earth’s rotation?

[YT2095]

your speed through the Air will be the same in Any direction (all things being even and ignoring head or tail winds).

Of course this is because the air is moving along with the earth — it would be a tad windy if it were otherwise.

[YT2095]

just a bit, yeah

[TimbaLanD]

lets say you jump up say around 20m and you dont land say for 5 yrs... will your position change when you land in back on earth?

I think it won't (or small) since the velocity of earth is constant (well not entirely)!

you could do this on foot at the poles. Just walk around in a circle in 24 hours. you'd get pretty cold, though :0)

[YT2095]

Yes, it will have to change, as you`ll require a horizontal velocity sufficient for orbital insertion (albeit a very low orbit).

 

unless you have some Other idea of how you`ll stay in the air for 5 years? which is fine, I`ll just move this thread to Pseudoscience if that`s the case

 

another way to consider it is this, in order to stay up in the air for that long would require you to be "Anchored" to something, and so even if it WAS a Magik Helicopter or something, That then uses Air as the anchor.

if you were on a string tied to the moon (or other celestial body), then yes you would start moving relative to the earth.

maybe that`ll help some more too?
