Let's just talk about Earth. The earth's diameter is 12756 km. Its circumference is pi x 12756 = 40074 km. The earth spins 1 round in 24 hours. That's 1700 km/h, or 472 m/s. If it rotates in an OPPOSITE direction, it's like the Earth is rotating at 944 km/s and suddenly stops. What happens? You fly through the air at 944 km/s. All the houses fly through the air at 944 km/s. Whole forests fly at 944 km/s. Even whole mountain ranges and mountain tips fly at 944 km/s. The ocean's waters fly backward at 944 km/s. Talk about a uber tsunami. I don't know what the friction of air against these object would do to them. Can anyone solve that? Even the Earth's crust might become detached with its outer mantle, I think. Lava breaks out everywhere, global earthquakes... In short: All hell breaks loose. Man, that's even worse than the Death Star. Superman actually does that to Earth in one of his movies. He's a major nut!

I'm not sure I really understand your question.  Are you how fast a particular point on earth is moving?  If that is the case it's not an easy answer because it depends where you are on the planet.  If you are on one of the poles then there is very little rotational speed.  If you are on the equator then your velocity is much greater.  Think of it like a CD in a CD player.  Also you would need to factor in the speed of the earth as it travels around the sun sometimes spinning in the same direction the earth is traveling resulting in a greater total velocity and sometimes spinning in the opposite direction yielding a lower total velocity.  The final analogy would be to tie a CD player to a string and swing it in circles while the CD is playing.  The speed of a single point, other than the center, of the CD is constantly changing.  However, it's still not even that simple due to the earth's eliptical orbit and varied velocity.

That is how long it takes the Earth to rotate once on it's axis.

Ask your son to turn around in a circle once per day.  That is the rate  of the earth spinning.   One rotation per day.  Did he get dizzy?  \n\nSpinning is angular speed or angular frequency( the rate it turns through an angle), not the speed, tangent to the circumference of the earth.\n\nThe earth spinning is improperly linked to 1000 mph.  The earth spins one time per day.  The surface velocity is 1000mph at the outer surface of the earth, but that is just like going straight at 1000mph.\n\nThe surface speed of the earth is undetectably with out a frame of reference.  Just as speeding in a car...without looking out the window, you don't know if you are moving that fast.  We only detect a change, acceleration.  The earth spins so slowly, we don't detect the angular frequency as being dizzy.

This is not true, but widely circulated as fact.\n\nI quote verbatim from snopes:\n\n"Because  \n\n   the Earth is a globe spinning on an invisible axis, a point at its equator will make a circuit of 25,000 miles in the space of a day, but any point not on the equator will make a shorter round trip; the closer that point is to either of the poles, the shorter its trip will be. Put another way, a pencil     at the equator travels 1,030 miles an hour, whereas another at Sarasota, Florida, moves at 930 miles per hour, and one at the North pole doesn't move at all. \n\n This apparent difference in speed results in the Coriolis force, an effect that imparts a twist to largish events happening away from the equator. Best known is its effect on air masses: as they move away from the equator, their speed (which matches that of where they started from) appears to be faster than that of the surface over which they are traveling. This sets them turning in a clockwise twist in the northern hemisphere and a counterclockwise twist in the southern. (Before you complain we have that backwards, please click here.)  Likewise, a cannonball fired due north will veer a teeny bit to the east, and one fired to the south will deflect ever so slightly to the west, something a skilled gunner would make an adjustment for. \n\n The twisting effect of the Coriolis force is real and does influence certain large things like the movement of air masses, but the effect is so small that it plays no role in determining the direction in which water rotates as it exits from a draining sink or toilet. The Coriolis effect produces a measurable effect over huge distances and long periods of time, neither of which applies to your bathroom. Toilets and sinks drain in the directions they do because of the way water is directed into them or pulled from them. If water enters in a swirling motion (as it does when a toilet is flushed, for example), the water will exit in that same swirling pattern; as well, most basins have irregular surfaces and are not perfectly level, factors which influence the direction in which water spirals down their drains. The configuration of taps and drains is responsible for the direction of spin given to water draining from sinks and bathtubs to a degree that overwhelms the slight influence of the Coriolis force. \n\n The belief that the Coriolis force influences the direction in which water drains from plumbing fixtures is widespread and has been repeated as fact in a number of venues, including popular television shows (such as world traveler Michael Palin's Pole to Pole) and even in textbooks.  We can only speculate on why people are so enamored of this snippet of misinformation, guessing that it has something to do with the desire to find some of the mysteries of science in the realm of the everyday.

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.

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.

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.

(a) The angular speed of the earth is the circumference of the orbit divided by the time taken to complete one orbit.\n\nAngular speed = (2*pi rad) / 3.16x10^7s = 1.987x10^-7 rad/s. \n\n(b) The tangential speed is the same as the angular speed, but in different units (probably m/s).\n\n1 rev/yr * (1/3.16x10^7) yrs * (2*pi*r)m/rev = 29810 m/s\n\n(c) The magnitude of the centripetal acceleration is the radius times the angular speed squared.\n\na = r*w^2 = 1.50x10^11 * (1.987x10^-7)^2 = 5.924x10^-3 m/s^2\n\nThe direction is toward the sun.

hold on here, this isnt a short answer - \n    the Earth is on average 92Million miles from the sun, times pi for the circumforance and its roughly 290Million miles around.  divided by 365 for the number of days, the earth travels some 790,000 miles on one day, ya thats high on the odometer.  distance in one day divided by 24 hours comes to 33,000 MPH, now i did this on my computer but it does seem right, \n\nNow part 2, hang on here, big numbers ahead, the Solar System wihich Earth belongs to is roughly 26,000 Lightyears from the galactic core, (which has a Supermassive Black hole as heavy as 6 Trillion suns).  it take a quarter of a Billion years (250,000,000) for our solor system to complete one revolution around the galaxy. The circumferance could be some 80,000 Lightyears,  though i am not sure how to calculate the speed of the solar system.

Hint: The Earth revolves 7.5 degrees every 30 minutes.

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.

Since the Sun is made of gas, different parts of it rotate at different speeds. Near the Sun's equator, it completes one rotation every 27 Earth days. But near the poles, it's about 31 Earth days. This is called "differential rotation". \n\nHope thats clear??

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...
