Lets see now, Earth rotates aproximately once every 24 hours, thats one over 60 x 60 X 24, thats one over 86400 rotations per second. All the time we are doing that, consider this, we are also going around the sun at aproximately 66500 miles per hour.

The earths rotation is slowing down therefor the days are getting longer i believe the diference is like .0026 sec per day or so.  at any rate every year or perhapse 2 years we have a LEAP SECOND that is calculated in to the time change i cant remember the exact ammount   you might find the answer on \nwww.drdino.com the man who runs it is a former school teacher who debates evolution named Kent Hovend  the "leap second" is part of the explanation he uses to debunk evolution.  you might try asking him. if you need exact info.

The Earth is about 12,750 kilometers (km) in diameter.\n\nHere are some answers to some more of your questions:\n\nHow old is the earth?\nThe earth is about 4.5 billion years old. That is 45,000,000,000 years. The sun, the moon, the planets, and nearly everything in our solar system was formed at the same time, so they are all 4.5 billion years old. \nHow does the earth spin?\nIf you look around at planets, stars, and galaxies in the universe you will see that EVERYTHING spins! This is because planets like Earth (and stars and galaxies) formed from a large cloud of gas and dust. As gravity pulled the cloud together, any little bit of spin gets multiplied. This is known to scientists as the Conservation of Angular Momentum. You can try this out yourself. Find a chair that spins easily and sit on it. Start out by spinning with your arms outstretched, then pull them in to your body. Did you notice that the chair started to spin faster when you pulled your arms in? The same thing happens as the planet forms — as its gas, dust, and rocks fall together the planet spins up faster and faster. Later other things can affect the spin. Earth and the moon pull on each other, affecting both their spins and the orbit of the moon. It's quite a dance! \n\nHow fast is the earth spinning and why can't we feel it spin?\nThe circumference of (distance around) the earth is 2 x PI x radius, which turns out to be about 24,000 miles. Since the earth turns once per day (or 24 hours), that is 1,000 miles per hour! We don't feel that because everything else is moving with us and because the motion is very, very smooth. It's kind of like sitting in a car and reading a book or playing a game. If the car is going very smoothly, with no stops or bumps, and you don't look out the window, you wouldn't know you were moving. The only reason we know the earth is turning is because the sun and stars move across the sky. \n\nWhat is the exact tilt of the earth? How much does it change throughout the year?\nThe tilt of the earth is 23.45 degrees. This is measured as the tilt of the earth's equator compared to its orbit around the sun. The amount of the tilt doesn't change with time, but the direction that the earth's poles are pointed does. This is called precession. It is just like the wobbling of a spinning top. The direction that the North Pole (and South Pole) is pointed moves in a circle in the sky very slowly, completing each circle once every 26,000 years. \n\nWhy does only Earth have so much oxygen?\nThat's a very good question — no other planet in the solar system has so much oxygen. The answer is — life! Earth did not originally have a lot of free oxygen in the atmosphere. The oxygen was mostly combined with other elements to make carbon dioxide, water, or in rocks. But as early life evolved, especially plants, well they give off oxygen. So the reason we have so much oxygen in our atmosphere — and we are here and can breathe it! — is due to plant life on the earth! \n\nHow can rockets get through the earth's atmosphere, but comets can't?\nObjects hitting our atmosphere usually burn up because they are hitting it so fast. Usually they are moving at hundreds or thousands of miles per second. Rockets and the shuttle move more slowly (although pretty fast compared to cars on the highway). Here's a comparison. If you jump into a swimming pool from the high board and hit the water really hard, it stings and you make a big splash. But if you step into the water slowly, it feels fine and you make only a little ripple. The same thing happens to meteors — they hit the earth's atmosphere real hard and go splat! \n\nIf a comet hit the earth, what would happen?\nIt could cause a big explosion. The nucleus of a comet is thought to be a mile or two in size. The nucleus is made up of ice and rock, but we aren't sure how solid it is. Something that big hitting the earth from space would be bigger than

The earth's rotation does slow down, but not\ndue to the reason you are stating... gravitational\npull of the moon and sun causes more mass to move\ncloser to the surface over time. When an ice-skater\ntwirls around, if the pull in their arms to their\nsides they spin faster, when they push their arms\nout they slow down - in the same way, the earth\nis slowing down, but only by about 1 second per\nseveral years, which is adjusted for by adding\na leap-second from time to time to the atomic \nclock.\n\nThe earthquake in Sumatra on 26-Dec-04 resulted\nin a massive chunk of the ocean floor collapsing\ndown (closer to the earth's center), which caused\na measurable speeding up of the earth's rotation.\nThis was, however, not sufficient to compensate\nfor the otherwise slowing down trend, and only\nmade the adding of a leap-second get delayed...

The earth spins at about 1100 miles per hour at the equator (26,000 miles in 24 hrs) so stopping fast would be very distasterous to all living things. Remember, everything not locked down on earth would try to keep going 1100 mph! Imagine the ocean water going 1100 mph & slamming all the coastlines! From a human perspective, it would be very exciting for a second or two, then we'd all be flying with debris all around us that suddenly is going 1100 mph. I'd imagine lots of trees & rocks & bricks & wood & cars & metal, it would not be fun... Eventually we'd land on the ground or hit a mountain or something that stopped along with the earth. We'd then go up to heaven or nirvana or whatever religion place we go when we die. I would think things like seeds, bacteria & bugs would survive - but I'm only guessing given the way all the weather, land & seas would be changed. I doubt gravity would change very much but nobody would be alive to check...

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.

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.

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 :)

OK, you are right, there are 2(pi) radians in a circle and spinning 10 times is 20 radians.\n\nYour angular velocity is the rate the mass (the clothespin?) spins within a given time. You give 10 revolutions in 5 seconds. or you can say 2 revolutions per second or 120 rpm (revs per minute). Multiply that by 2 to get radians per minute. \n\nAngular acceleration doesn't seem to be considered here since you say the mass has spun 10 times at a constant rate (or speed). So, in what you are asking, the length of the string (the radius of the circle of which the mass spins - your half a meter) Does not come into play here.

For one thing, it takes the earth 24 hours to complete one full rotation, and the earth has circumference of roughly 24,000 miles, which means the speed of its rotation is appx. 1000 mph...\n\nSo if we did not have a protective atmosphere as we do, winds could be up to 1000 mph. Fortunately we do, so the winds we do experience are usually negligible...

False.  m/s (meters per second?) is not a measure of rotary speed.  Until you get that straightened out, no answer can be calculated for a) or b)\n\nBefore posting a ?, do a search here.  This same ? came up yesterday.........!

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.

The earth turns with respect to the motion of force which was placed upon it with in the vacuum of space, and also with respect to the vacuum of space there is no friction to slow it down, therefor it shall continue to spin forever if it's motion is uninterrupted, or unaltered by another matter energy object of aether large size, or fast speed impacting it with direct respect to the angle of the interaction.\n\nas for your second question the axis is the center point at which the spin turns, and is therefore recognized by us with respect to the earths motion spin as the axis, and if the motion and direction of spin were changed tomorrow to be perpendicular of that which it is today, then the new axis would be perceived tomorrow as existing at some point at which we recognize the equator today.

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.
