If the earth is round , do we fly around the earth to get to another country on the other side ?

Well what else are you going to do, fly through it?!?!

I have flown from Anchorage Alaska to Boston Mass a couple of times, and the flight time from one direction to the next does not change.  The earth is spinning, but so is the air that surrounds it.  If you are flying across the northern half of the country its faster to fly east because of the jet stream

You would need to travel at the same speed as the Earth rotates, but also take into consideration the distance you have to travel due to the circumference of the Earth. I.E. If you were on the equater you could work it out easy...take circumference of the earth at the equator (40,000Km) and you know you want to stay in the same spot so for one rotation its 24 hours,  speed = distance over time so at the equator your speed would need to be 1666 Km/h. However because the circumference is smaller at Latitude 51 32N (London) The speed would need to be reduced. But by how much im not certain as I dont not know the relationship between the two circumferences\nHope that helps

The earth's approx circumference at equator is 24,800 miles.  It takes about one day for it to spin around once.  So, at the equator one would be zipping right along at approx 1,000mph.  It gets slower the further north or south of the equator you go since the "circle" of latitudes gets smaller.  So, do we move fast? We do, but since we are part of the gravity well created by the earth, its spin is our frame of reference and relative to us we are not accelerating out of it.  Gravity and accelerated motion are covariant (thanks to Einstein) and an internal observer cannot tell one from the other.  Just like going along in a car.  If the car could travel extremely smoothly enough and you could not see any external input--like out the windows, unless it changed direction or speed i.e. its velocity by undergoing acceleration, you would never know you were moving. Think about it you can only really tell you're moving along by the road vibrations in the vehicle and by seeing things going by outside the windows.  You only feel "moved" if it turns or speeds up/brakes.

They are in space.. so it depends from what angle or where are you looking as a whole picture. Since we are on earth, we take earth's orbit as the reference and draw the other planet's rotation. But from outside in space (outside earth), if you are positioned perpendicular to earth's rotation, then earth is rotating in vertical direction.. thats what i could imagine..

If that direction were opposite the direction of the \nearth's rotation, I think the answer is theoretically yes.\nIn reality there's not enough mass of people relative to the mass of the earth to have any effect.

The geometry of the universe is non-euclidian. if you carry on going in a straight line you will eventually come back to your starting point.

I believe earth is indeed round, as seen from outer space, and that people have gone to the moon.\n\nContrary to popular belief, the Bible doesn't say that the earth is flat. I think Infrared Loaf is stretching the text.

Because the Earth is round, the widest point could be from top to bottom.... it all depends on which way you are looking at it.

i am round\nlike earth

Dependant upon the altitude of the craft together with it's power, we can choose the speed in which we can cecum navigate the planet.\nThe craft will take off and land in the same way, we can travel around the planet in any direction and choose the speed, but if we were to leave the earths atmosphere, we then control our exit speed and aimed in the direction we require, we would then be able to use the speed of exit. to travel great distances in less time and with less fuel.\nIf we stay within the earths confine, but at extreme altitude, we can then travel at greater speeds.\nGo to the NASA site and look up scram jets.

The earth is APPROXIMATELY round due to gravitational forces.

Know what? The answer is "yes", we could and would change the rotation of Earth. If every wheeled vehicle simultaneously accelerated eastward, Earth's rotation would slow a bit, and if they accelerated westward, it would speed up.  You can calculate the amount, it's actually a pretty simple physics application, starting with say 1 billion 3000-pound vehicles, say all of them spread out along the equator, all accelerate at 1 G, and given the mass of Earth, which is easily look-up-able.  Of course, we're probably talking a change of only picoseconds or maybe only femtoseconds per day, but it is a true and calculatable, even theoretically testable change.  Also note that friction, both during the mass-acceleration and especially once everybody hits the brakes, will impart the opposite force, resulting in a zero net gain.  In other words, a temporary, but no permanent change in rotational speed is possible under this scheme, unless somehow the vehicles, while accelerating, attain a speed sufficient to launch them into space at escape velocity.  Then their effect on Earth's rotation can remain behind as permanent.\n\nInteresting thought, huh?\n\n[Below added after reading the 2 posts below]\n\nOkay, I took a crack at the math, thank you wikipedia for the definitions and equations:\n\n1 billion cars of average of 1000 kilograms each, lined up along the equator accelerate simultaneously from a dead stop at a rate of 1G (32ft/sec^2).  Their combined net torque looks to be a force of 10^12 kg, approximately equal to 10^13 Newtons. If I understand wiki correctly, the change in the speed of the rotation of Earth (in radians per second) will be the previously-calculated torque divided by the moment of inertia of Earth, which should be:\n\n(2/5)(6*10^24)(13*10^6)\n\n so the change in speed will be:\n\n10^13/[(2/5)(6*10^24)(13*10^6)] radians per second =\n0.3*10^ -18 radians per second that the cars accelerate at 1G.  If they can do that for just 10 seconds, the change in Earth's rotation would total  3*10^ -18 radians per second, or .26*10^ -12 radians per day.  Earth's rotation is about 24*10^12 times faster, so I think altogether that works out to a net change of 3.6*10^ -9, or 3.6 picoseconds change per day in Earth's rotation?  Tho I pretty sure I've made at least a couple of mistakes along the way, I gotta love how that agrees with my original guesstimate above.\n\nJeeez, it's 2 in the morn - I really DO need to get a life...

WHEN YOU ARE ON EARTH U CANT FIND ANY POINT. YEAH I THING IS POSSIBLE. U CAN PURCHASE A GLOBE AND ROTATE IT. U WILL FIND ROTATION THERE.!

That depends on which side of the planet you're on...

if I am going around the earth I am orbiting.\n\nIf my orbit becomes one where I am travelling downwars towards earth....for some reason...then my orbit is a decaying orbit.....its broken out of that intial "ok" orbit of the earth...

That depends on where on Earth you are standing. At the poles, the Earth hardly spins at all, but as you travel towards the equator, the rotational speed picks up. This makes sense -- as the circumference of a circle increases, a single point along it has to travel faster to complete a revolution in the same amount of time. \n\nThe rotational speed of the Earth at the equator is about 1,038 miles per hour. The atmosphere at the equator is also slightly thicker due to rotation, and you weigh slightly less. At mid-latitudes, the speed of the Earth's rotation decreases to 700 to 900 miles per hour. \n\nIf the Earth were to stop spinning suddenly, the atmosphere would still be zipping along nicely at around 1,000 miles an hour. As a result, everything not attached to bedrock would pretty much be scoured clean. \n\nThe circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour. \n\nMultiply by cosine of your latitude to see how fast the Earth is rotating where you are. \n\nHope you get an A if you are doing a science project haha.  Or hope you learned something :)
