Is revolving of earth affects the flying time of a flight from west country to east country and vice versa?
453022
no, as the atmosphere actually moves with the spin and the aircraft moves within the atmosphere, however stratospheric winds ( winds in the level of the atmosphere that the aircraft travel in) do affect travel time, for example a flight from say UK to Singapore takes 13 hours, from Singapore to UK takes 11 hours (aproximate) , depending on headwind, or following wind.

I have debated this once with another knowledgable person. We came to a conclusion that any calculation/prediction is applicable at only time. This time has different representations in different time zones.\nTo explain a little further. These effects are caused because of a planetary/celestial body movement. That happens at a particular instant (assuming a global time - ofcourse this is a violation of laws of relativity). So if the effects are predicted for 12 noon PST then it is valid in India at 12:30AM the following day and so on...

This is due to relative velocity. It's a great concept...it's the same concept which applies to you sitting at your desk..believe it or not...the earth you are situated on is revolving at the rate of once everyday..but do you feel it?? Nope...that is because you are revolving with it at the same speed. The formula for relative velocity is Vu-Vo where Vu is your speed and Vo is the speed of the other car..since they are the same, you subtract and voila..you get zero..therefore the car appears to be moving at zero speed in your vision. Check out relative velocity on GOogle..its a fun topic and your question is the fundamental base to relativity...Wow huh??\n\nGood luck.\n\nAyerhs\n\nPS: it is most definitely not because they have it on cruise control..I mean they could if they wanted but thats not the reason that they seen stationary to you.

Yes.  One ROTATION is one day (which varies for whatever planet you're on...for Earth it is 24 hours)\n\nOne REVOLUTION is one year for the planet (again, varies for each planet...earth is 364 1/4 days...and the reason for LEAP YEAR).

The land does not move beneath us.  What are you talking about - the revolution of the Earth on its axis?\n\nIf that is the case, please take note, as I have seen nobody answer this frequently asked question correctly.\n\nIf you turn round quickly on the spot, you'll soon get dizzy, even though no part of your body is moving much more than a few miles per hour.\n\nIf you drive around a traffic island at 60 mph, you will throw your passengers all over the place.\n\nIf you drive around the city loop at 60 mph, you will hardly notice any turning forces.\n\nSo, speed is not the critical factor in how turning affects you.  What affects you is the rate at which you are changing direction. \n\nWith the Earth taking 24 hours to turn once, at any point in time you are not changing direction hardly at all, and from minute to minute you are travelling in a straighter line than a draughtsperson could draw.  \n\nTravelling in a straight line at constant speed has no effect on you at all, even if it is 1 million mph.

It has to do with the direction the earth rotates on its axis. It rotates once every 24 hours. So, the direction it spins is the direction the sun passes by. The earth would have to completely stop and start to rotate in the opposite direction in order for the sun to rise in the west and set in the east. Hopefully that won't happen any time soon, because it would probably mess gravity all up.

I suppose you know the air moves from high pressure to low pressure. The more difference in pressure the faster the wind.\nHowever the rotating earth gives complications. On the Northern hemisphere wind gets a deviation to the right (looking in the direction of the wind). This is the law of Buys - Ballot.

If you are on the same planet that I am, yes!\n\nThe earth rotates counterclockwise on its axis. Therefore the sun will always "rise" in the east. The reason I put rise in quotes...b/c the sun doesn't actually rise. It is from our perspective that it seems to rise.\n\nThe only way you will see the sun rise in the west...\n1. you are on Venus (clockwise rotation)\n2. a major astroid strikes earth & changes earth's rotation so that it goes clockwise. But the problem here is that your chances of still being around to see it is nil.\n\nAlso, all the planets in our solar system have a counterclockwise revolution path around the sun.

Yes, it does, but by a very negligible amount.\n\nDue to the law of conservation of angular momentum, the Earth has some over all value for its angular momentum (and for that matter, so does the solar system and our entire galaxy, ... as well).  As thr plane is flying around the Earth, it has some angular momentum too, different from its original value just sitting still on the surface.  In order for the overall angular momentum of the Earth to remain constant, the Earth's rotation is effected ever so slightly.\nHowever, the effect is so small, it is not even noticible when we are talking about objects as miniscule as an air plane compared to the Earth.\nAlso, since, over all, on average, for every plane flying one way, there is another plane flying the other way (or when the plane returns), so the effects are all canceled out.\n\nIt is the same principle at work is your on a merry-go-round and you move closer in to the center or farther away (or in this case, around while spinning on the merry go round), angular momentum needs to be conserved, it is the law.

Only if the plane has engines with sufficient thrust to hold it up against gravity, and it orients itself engines-facing-down to hold itself there -- the most recent jet fighter for the US Air Force can do this, as well as some "jumper jets", but not any other planes and certainly not any commercial airliners can.\n\nRelative to the ground, a plane can be "still" if the wind speed aloft is above the plane's stall speed.  In that case, air is moving across the wings of the plane at a fast enough speed to give enough lift to keep the plane aloft even though it doesn't move relative to the ground (the thrust from the engines and the "headwind" balance each other out).\n\nYou can get a good sense of this if you fly a lot between the pacific coast of the US and Asia -- the strong jetstream across the pacific does funny things to "ground" speed.  When flying west to east (with the jet stream), indicated ground speed on flights I've been on has exceeded 1,000 MPH, even though the plane can't go more than 400 MPH or so with no wind.  And flying east to west, indicated air speed will sometimes be as low as 50-60 MPH, even though airspeed is still 400MPH -- that headwind jetstream is a killer, and significantly lengthens the time it takes to get from LA to Tokyo (the normal 11-hour flight once took us 16 hours because of the headwind!) -- though I've made the return trip in under 7 hours!

Yes and No.\n\nYes, the Coriolis effect is real, but is extreamly weak and does not influence us on an everyday basis.\n\nThe Earth's rotation does effect to a very minor degree the direction in which water will drain, the farther away from the equater you are, the more influencial the force it.  However, the Coriolis effect is negligible in everyday life compared to other influences such as any other disturbances in the water, wind, ....

His definition is a little odd, and does not seem to follow from his example (which is more about motion than position on the earth).  Technically, his motion relative to stationary students would make time pass at a different rate according to all that Einstein stuff (though there's no way he could ever notice the tiny difference).  But that would be true without any reference to the earth and the sun.  Is he trying to make a different point -- that his days would be longer because the sun would set later for him because he is walking toward the west where the sun sets?  If so, he's right that his days (defined as revolving around the Earth's axis) would be longer, but that would not mean time was moving at a different speed for him; it would only mean that the sun would set a little later from his visual perspective -- just like you can gain or lose hours when you cross time zones in an airplane; you reset your watch, but that has nothing to do with the passage of time.  Unless you are defining time only by calendars and clocks and common agreement.

Lots of unnecessary complications here.\n\nAirspeed is the hypotenuse. 20.4 is the side opposite the angle we are looking for.\n\nThe heading, east of north, must be at angle sin^-1(20.4/241).\n\nSpeed relative to the ground is the third side of the triangle, and is \n\nsqrt(241^2 - 20.4^2)\n\nZidane has got the angles all wrong. The wind is from the east. We want to fly due north. That's where the right angle is. 241 is the hypotenuse of the triangle. The wind serves to make the ground speed less than 241, not greater.

None, the two are not related. Earth's rotation is a measure of time and light years are a measure of distance.

We travel an average of 1,000 miles per hour at the equator.  Because everything around us is traveling at the same speed, we do not perceive motion.  The further north (or south) from the equator the slower you travel.  At latitude 60 (mid Canada) you are traveling half as fast.  Still, the relative motion of everything makes it seem like we are standing still.  Just like when you are in a jet airplane.\n\nJust a side note about gravity as some people mentioned:  Gravity exists because of the mass of the earth, not because of spinning.  If we were to stop spinning (which in reality we are slowing down gradually) the sun would appear stationary in the sky.  Planet Mercury has a day that lasts much longer than one of our years.  It's rotation and orbit almost always keeps the same side towards the sun.  Imagine waiting a day on Mercury.

Travelling east or west across several time zones at high speed causes jet lag.\n \n* Jet lag is a temporary disruption of normal circadian rhythm caused by high-speed travel across several time zones typically in a jet aircraft, resulting in fatigue and varied constitutional symptoms.\n\n* The maximum jet lag a person can experience is 12 hours. If the difference in time between two places is greater than 12 hours, subtract that number from 24. For example, there is a 16 hour time difference between Los Angeles (standard time) and Hong Kong. Thus, 24 − 16 = 8 hours of jet lag. The person will incur the same amount of jet lag as someone traveling between London and Los Angeles, where the actual time difference is 8 hours. Disregard the difference in date if flying across the International Date Line.\n\n* The condition is not linked to the length of flight, but to the transmeridian (ie, East-West) distance traveled. Hence a ten hour flight between Oslo and Johannesburg is less inducive of jet lag than a five hour flight between New York and Los Angeles. There is no firm agreement as to which direction of travel is worse. Some believe that travelling east is worse as it "accelerates" the passage through various time zones (a night might only last 3 hours when flying east), and because the symptoms of travelling west, such as waking earlier in the morning, can be easier to integrate with ordinary life. Others counter that the impact is worse when one travels away from one's "habitual" time zone, and is minimised when returning to it.

Why shouldn't they be the same?  The distance between the Earth and the Sun doesn't change much in one day.  And even if you argue that the rotation of the Earth gives is a relative speed that should be added to (or substracted from) the speed of light, you're forgetting that the speed of light is a constant.  You can't add or remove anything to it.  If you're on a train going at the speed of light and you turn on a flashlight, the "total relative speed" of that light won't be twice the speed of light.\n\nAs for how can this speed me mesured, there's an experiment that uses mirrors and a laser.  Those flat mirrors are glued around a cylinder and they rotate.  (It could also be a rotating screen with holes in it.) When the mirror is positionned right, the light comes back to the laser.  Knowing the distance between the mirror and knowing the frequency of the rotation, we can calculate the speed of light by mesuring how much times it takes for the light to go to the mirror and come back.  TRY FIZEAU OR FOUCAULT ON GOOGLE.  He's the guy who did that.
