what is the speed of earths rotation?
537517
The speed at which the earth spins varies upon your latitudinal location on the planet. If you're standing at the north pole, the speed is almost zero but at the equator, where the circumference of the earth is greatest, the speed is about 1,038 miles per hour (1,670 kph). The mid-latitudes of the U.S. and Europe speed along at 700 to 900 mph (1125 to 1450 kph).

accoring to space.com, if the earth stopped rotating suddenly.Our atmosphere would still continue to rotate at aprox 1000 mph, obliterating everything on the surface, basically the entire earth would turn into a sandblaster.

It takes anywear from 8-9 min! The reason being that the earth does not revolve around the sun in a perfect circle. This answer only counts if I interpreted your question correctly.If not the speed of light itself does not travel.

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.

KE = 1/2 mass* v²\n\nThere are two velocities.  One is spin energy, however this is a tricky one since velocity is relative to radius and polar angle.  The other is the energy of the motion around the sun, which is somewhat easier to calculate.  The earth's velocity is 30 km/s, so:\n\nKE = 1/2M* (30 km/s)² = 450M (km/s)²\n\nFor spin energy:  KE = 1/2Iω²\n\nWhere I is moment of inertia and ω is angular velocity.\n\n"As an example, let us calculate the rotational kinetic energy of the Earth. As the Earth has a period of about 23.93 hours, it has an angular velocity of 7.29×10-5 rad·s-1. Assuming that the Earth is perfectly spherical and uniform in mass density, it has a moment of inertia, I = 9.72×1037 kg·m2. Therefore, it has a rotational kinetic energy of 2.58×1029 J."

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 :)

Earth is rotating at a speed of about 1100 miles per hour. If our planet suddenly stopped rotating, the atmosphere would still be in motion at that speed. The atmosphere would be moving so fast it would literally sweep the land masses clear of anything not anchored to bedrock, this would mean rocks, soil, trees, buildings, people and animals. All would be swept up into the atmosphere.\n\nIf the Earth's rotation slowed down gradually over millions of years, and this is the most likely scenario, it would be a very different story. If the Earth slowed down to one rotation every year, called synchronous rotation, every area on Earth would be in either sunlight or darkness for one year. This would be similar to what the Moon goes through where for two weeks the front side of the Moon is illuminated by the Sun followed by the front side being in darkness for two weeks.\n\nBut what if the Earth stopped rotating completely? In that case, one half the Earth would be in daylight for half the year while the other side would be in darkness. The second half of the year it would be reversed. Temperature variations would be far more extreme then they are now. The temperature gradient would affect the wind circulation also. Air would move from the equator to the poles rather then in wind systems parallel to the equator as they are now.

I guess you don't know how fast the Earth spins.\n\nFind that out and you will have a different question.\n\nHOW FAST IS THE EARTH SPINNING AROUND ITS AXIS?\nThe Earth is spinning around its axis. At the equator, the Earth's surface moves 40,000 kilometers in 24 hours. That is a speed of about 1040 miles/hr (1670 km/hr or 0.5 km/sec). This is calculated by dividing the circumference of the Earth at the equator (about 24,900 miles or 40,070 km) by the number of hours in a day (24). As you move toward either pole, this speed decreases to almost zero (since the circumference of the spinning circle at the extreme latitudes approaches zero).

First, the speed of the rotation of the earth relative to where you are on the earth.  At the equator, the circumference of the Earth is roughly 24000 miles.  This is convenient, because the Earth rotates about its axis once every 24 hours.  Therefore an hour = 1000 miles of equatorial rotation.  Understand the fastest moving part of the Earth is the equator, since an object on the equator travels 24000 around the earth's Axis every day.  If you are closer to the poles, you are on a "thinner" slice of the earth, where the circumferene may only be 20000miles.  In that case you are moving at 833 miles per hour.  The fact that the Earth moves faster at the Equator than at the poles is responsible for the Coriolus Effect which is really important to people who study meteorology, or who wonder why their toilets get all swirly when flushed.  Why we don't "feel" the rotation is, simply put, because we are rotating exactly the same way as the earth.  In physics, this is called a "frame of reference".  For most intents and purposes, the earth is at "rest" relative to us.  As a human, you make up part of the mass of the earth, and you spin with it in a constant rotation.  It's only when we look to things that are not directly connected to the earth that we really see the effects of it's rotation (ie Tides of water, moments of clouds and weather, etc. . .)  Hope that helps.

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.

Assuming a big ring that rotates, we need to fix the radius and the velocity out on the edge.  The acceleration toward the middle (which causes the feeling of gravity) is given by\n\na = v^2/r\n\nTo match gravity on earth, assume 9.80 m/s^2\n\nYou can make the radius what ever you want.  Assume 100 meters.\n\nThen 9.80 = v^2/100.  So, v^2 = 980.  v = 31.30495.\n\nSo, how fast is it spinning?\n\nThe circumference is 2*pi*r = 2*100*3.14159 = 200*pi.\n\nThe time it takes for it to do one rotation is:\n\n200*pi (meters)\n--------------------\n31.30495 (meters/sec)\n\n= or 20.07088 seconds.\n\nThe angular velocity is 360 deg/20.07088 seconds = 17.9364 deg/sec\n\nor, 2pi radians/20.07088 = .3130495 rads/sec.\n\nNotice, this is exactly what you would have gotten by taking v/r and getting the angular velocity.  I don't know if you are studying that part of rotational dynamics yet.\n\nSo, the bottom line is, as long as v^2/r = 9.80, you can then get the rotational velocity in radians from v/r.

Earths rotational speed is near 1000 mph.\n\nEarths average orbital speed around the sun is near 67000 mph.\n  (Faster in January, slower in July)\n\nEarths speed around the galaxy is about 700000 mph.\n\nSpeed is a relative concept. Your speed must be computed relative to some other object or frame of reference. However, I would assume you are refering to orbital speed around the sun. In which case 60000 mph is basically correct.

The Earth is approximately 25,000 miles in diameter at the equator, and it spins once in about 24 hours.  So, at the equator, the Earth is spinning about 1000 miles per hour.  However, if you live in the US, the Earth is moving much slower-about 70% the speed depending on your exact latitude-and slower as you go north or south from the equator.

The mean radius is 6371.0 km.  The radius at any latitude is equal to that times the cosine of the latitude.  The Earth turns once on it's axis in 23 hr 56 min 4.0989 sec, or 23.93447 hrs.\n\nIt takes that long to travel 2(Pi)(6371)(cos(lat)).  Divide that distance by the time above and you're in the ball park (neglecting the difference in polar and equatorial radii).\n\nNote: The figure given for the Earth's rotation is correct according to Astrophysical Data: Planets and Stars.  The 24-hour day is measured from noon to noon - in relation to the Sun.  The Earth kind of rolls around its orbit, so after it has turned thru one rotation it has also moved along its orbit.  It has to turn for another 53.9 sec past the full rotation for the Sun to be back to due south again.

Add v2/R.\nv=speed of rotation at the suface of the earth.\n(it depends on the geographic altitude fi)\nR = radius of the earth.

It can! Actually Earth's rotation is slowing by about 2.2 seconds every 100,000 years. The massive earthquake that recently caused the disastrous tsunamis around the Indian Ocean slowed Earth's rotation by a few micro-seconds. Don't worry, though, long before Earth stops spinning, our Sun will have left its current stable condition and engulfed the planet--in about 4.5-billion years.
