why the earth can able to circumgyrate in the 24 hour 40,000 km?

The earth is say assumed to be a perfect sphere.\nSince it rotates around itself, so every point on its surface moves with the same speed which is v say.\nIt traces its whole circumference in 24 hrs.\nIts radius is about 6400 km\nSo maximum distance traced is 2 * 3.14 * 6400\n                           =  40192 km.\n\nFor a plane of mass say m and let mass of earth be M\nvelocity of plane (V) is given by centripedal force.\n\nSo V = (gR)^(1/2)  ...... I agree that this is a bit physics. This is a reference to newton's gravitation law.\ng is acceleration due to gravity. R is radius of earth.\n\nI didn't quite get the second part of your question which involves the plane. But i hope a bit physics may help you. Post your question again systematically. I hope the first part of your question is answered satisfactorily.

the earth spins at 1500 mph.  If you take a ball and spin it extreemly fast you will find that the center of the ball will grow and the poles will flatten.  It is like driving a car very fast.  The higher up ion speed you go the lower to the ground it will become.  I has to do with Volocity.

The surface speed of the Earth's rotation at the equator is 465.11 m/s, while the average orbital speed is 29783 m/s, a good 6 times faster.  The orbital circumference would be 2AU*pi, where AU is the astronomical unit, the distance from the Earth to the Sun, or 149597870691 m.  So the circumference is 2*149597870691*pi = 939951143084 m, or 584058562 miles, which is very close to your answer; you probably just rounded differently or used a different value for AU.

Our moon is locked in what is known as a geo-synchronous orbit. For millions of years the angular momentum has stablized the moon to provide very little loss of energy between earth and moon. This does not account for the influences that the moon has upon our oceans though. (Tides) Our solar system has "moved about" for many millions of years to allow for efficient energy transfers between baryonic masses.  This is not unlike a person who sit's in a chair and move's about to become more comfortable.  Peace

By being eliptical, the earth is able to pick up speed when it comes towards the sun, and it's "slight shot"'ed away from its closest point to the sun.

The circumference of the earth at the equator is 24,902 mi / 40,076 km.

The Earth rotates once in 24 hours, and its (equatorial) radius is 3,963 miles (6,378 km). As with the Moon, the rotational speed starts at zero at either geographic pole and increases as you head toward the equator, where it reaches its maximum of about 1038 mi/hr (1669 km/hr). At 45 degrees north or south latitude, the rotational speed is about 0.7 of this maximum speed.

I'll assume it is your typical physics problem, which states some highly simplified conditions to demonstrate some physics principal and not a real engineering or natural science problem. We will assume the Earth increases its radius by 30 meters without any change in total mass, and that the Earth is a sphere of uniform density. In that case, the rotation rate would be proportional to the change in the moment of inertia of the Earth, I. For a uniform sphere I=2/5MR^2. You need to calculate the existing I and the new I after the radius change. Since M does not change, and we want only the ratio of the two Is, we can ignore the 2/5M and just compare radius. The radius of the Earth is about 6,370km or 6,370,000 meters. Adding  30 meters makes it 6,370,030 meters and the ratio of 6,730,030^2/6,730,000^2 is about 1.00001. That is about a 0.001% change, and about 0.001% of 24 hours is about 0.8 seconds. \n\nAs an angular momentum problem it is neat, but as a real life Earth problem it is totally bogus. There are all sorts of complications, like the sea only covers 70% of the Earth, the density of water is less than the average density of the Earth, the ice that melted started out far above sea level in many cases, and so on.

As we are not, the Earth is spinning at a pretty constant speed (1 rotation / day).  Based on the position we are on the Earth, we are traveling around at different speeds, the closer one is to the equater, the faster one is traveling.\nAt the same time, the force of gavity is pulling us toward the center of the Earth, this force acts as the centripetal force (NOT to be confused with the ficticious centrifugal force) that keeps us in circular motion.\n\nIf the Earth's rotation we to increase, the force needed to keep up down on the ground would need to increase too.  However, the force (gravity) is only so strong, it can only pull up down by some much.  So it one were to increase the spin of the Earth enough, it is possible for the centripetal acceleration to equal the gravitational acceleration....therefore we would be weightless.\n\nBut now the question is, what happens is we further increase the Earth's rotation past this point of weightlessness?\nIf you spin the Earth faster, our weight would not be enough to keep us in the circular motion we are currently in, so it would have the effect of seeminly lifting up off the ground.  HOWEVER, we would not fly up into space.  The moment we leave the ground, the centripetal acceleration needed is reduced (a = v^2 / r, when r increases, a decreases).  If we could maintain a constant speed once we leave the ground, we would eventually lift up enough to that we get to a height so that the centripetal acceleration equals the gravitational acceleration again and we would hover at that height.

No, the circumference is nearer 24,900 miles at the equator, if by planet you mean Mother Earth.

The circumference of the earth at the equator is approximately 24,902 miles.  This works out to about 40.16 times around.

We know that the Earth is 360 degrees(as the Earth is a sphere). Now the Earth takes about 24 hrs to complete a rotation or 360 degrees. Therefore in 1 hour, it will travel 15 degrees. But some times countries are so small that they don't even occupy 15 degree area. So its half - 7.5 degrees is taken into consideration. The main purpose of taking all this trouble is to make the calculation of time easier.

The earth rotates about its axis.  Obviously at the poles, there is no speed to the rotation at all.  At the equator, the circumference of the earth is about 25,000 miles and it rotates once per 24 hours, so the speed would have to be 25,000/24 = 1041.67 mph.  Depending on where you are between the equator and the pole, you'll get a speed of between 0 and 1041.67 mph.

The Earth orbits the sun at an average speed of 67,000 mph in a counterclockwise direction when viewed from above it's North Pole.

I will rephrase the question to make sure I understand it correctly.\nWhat I think you're asking is that since the earth is travelling around the sun at thousands of miles an hour, how can a plane keep up with that speed to stay in the earths atmosphere?  \nIt is a very good question.\nI will give you a scenario:\nIf there's a fly inside your car sitting on the dashboard, and the car is travelling at 70 mph, will it crash into the back window as soon as it takes off from the dashboard?  \nThe answer is no because the air inside the car is also travelling at 70 mph, along with everything else inside the car.\nSo, the fly will be operating in the atmosphere inside the car.\nThe same holds true for the plane.  The earth's atmosphere is travelling thousands of miles an hour along with the rest of the earth.  Therefore, the plane is operating inside that atmosphere and will be carried along with it just like the fly in the car.

No we don't have the ability now, not only is the temperature too great, there is way too much pressure for us to overcome. It would crush anything significant before we got to far. \n\nThe farthest down that we have been is only a few thousand km, and that with a tiny drill.\n\nThe deepest holes in the crust are natural. Volcanoes bring up material from tens of km depth. The crust thickness averages about 18 miles (30 kilometers) under the continents, but is only about 3 miles (5 kilometers) under the oceans. It is light and brittle and can break. \n\nHere is a great article that explains a lot:\nhttp://www.livescience.com/technology/050407_earth_drill.html\n\nThe reason we explore space more, is because not only is it easier to accomplish, but it is also far safer and less costly. I agree though that exploring below the Earth can be quite rewarding, but we simply can't do it as of now.

Hi Keenan!  Im Matt, an astronomy wizz.  If you look at most astronomy questions where I am, my answers are usually always the best of the best thanks to my power source, Blue Moons to Black holes By Melton Knocke.\n\nAnyway your question:\n\nEarth is moving fast, despite what people think.  It spins at about 1000 miles per hour, and goes 67 miles per hour around the sun.  You'd think that you would feel the spinning right?  WRONG!!!!  Sorry, cant help it.  Its so fun.  ANyway, the reason: All of the motions are almost completely constant. \n\nDon't get it?  Ever ride a train?  If you haven't, you can surely picture it as a car if you wish.  Notice how you feel abolutly no motion pretty much unless you speed up, slow down, or hit a bump?  Thats the same reason the earth never can be felt.  Its always going at a constant speed, never slowing unless it actually is hit with something dangerous enough to wipe out the human race.  \n\nThere is also another way in which we could indirectly feel the Earth's spin. Above we said that the Earth spinning is an example of almost constant motion. The reason we said "almost" is that the Earth's spin carries us around in a circle, not in a straight line. It's a very big circle, and it takes a long time to go around, but qualitatively it is the same thing that happens on a spinning amusement park ride, where it feels like you're being flung outward as the ride spins around. The spinning Earth is flinging us away from its surface a tiny bit, so that we weigh a little less than we would otherwise, simply because we are not being held down to the surface as tightly. \n\nAnyway, my answer is yours truly.  Enjoy!  Have fun.
