how fast does the earth spin?

Question

From outer space?

Answer 1

Our Earth is spinning at about 1,000 mph at the equator and less as we approach our poles. While we're on the subject, our Earth is also revolving around our Sun at 66,880 mph. Our Sun and our Solar System is revolving around the center of our Milky Way galaxy at 492,000 mph. Our Milky Way galaxy is moving within our local group of galaxies at 671,000 mph, and finally, our local group of galaxies is moving at 1,340,000 mph against the background of the universe. We should be really dizzy!

Answer 2

Q.1 The gravitational effect of the Moon orbiting the Earth while the Earth is rotating is causing the Earth's rotation to slow down (due to tidal effects). This energy must go somewhere so it goes into pulling on the Moon's orbit with the result to increase the distance to the Earth. It's a conservation of energy. Q.2 Yes, for the same reason as Q.1 (the Sun rotates as well and it is slowing). As well, the Sun is losing mass as it fuses hydrogen which also increases all solar system orbits. Q.3 Nothing to do with it.

Answer 3

Once a day!

Actually the velocity of the spin depends on where on the earth's surface you are. Near the equator, the movement is about 1000 mph, because the earth is roughly 24000 mi in circumference and it turns once every 24 hours. The nearer the poles you get, the slower the velocity, but there's still one turn a day.

Answer 4

it spins over 1000 miles per hour at the equator

Answer 5

1 time in 24 hours.
The speed at the equator is exactly 40,000 km / 24hours, being
(1666 + 2/3) km/hour.
At latitude y this speed is (1666 + 2/3) km/hour x cos(y)

Answer 6

One revolution per day!

or about 500 m per second

Answer 7

It depends on where on the earth you are.
17.5 miles a minute at the equator . 0.0044 rad/min"
