What is the speed the earth turns?

Answer 1

For rotation: The circumference of the earth is approximately 40041.47km, and this distance is covered in exactly 86400 seconds (the number of seconds in a day). Therefore, the earth turns at around .46344km in a second, or 1668.39km/h (or 1036.69mph).

For revolution around the sun: The earth orbit's radius is 1AU or 150000000km. Multiplying by 2*PI gives us a circumference of around 942477796km. This distance is covered in 365.24 days, or 31556736 seconds. So the earth revolves at a speed of 29.87km/s or 107518km/h (or 66808.59mph).

[Footnote: the 24 hour rotation is the synodic (relative to the sun) rotation of the earth. In fact, the earth completes one absolute sidereal rotation in slightly less time: 23 hours 56 minutes and 4 seconds, so relative to the fixed stars, the earth is rotating slightly faster than the figure given above.]

Answer 2

The earth rotates at 15 degrees per hour.

At the equator this is a linear speed of just over 1000 mph.

Of course, it depends on where you are. You can find the speed where you live by multiplying the cosine of your latitude by the speed at the equator. If the fact that where you are makes a difference sounds wrong, think about this: If you were at the exact top of the earth and drove a rod 1 inch in circumference straight into the ground (ice?), it would turn one revolution (1 inch) in one day, or 24 hours. So the speed attributable to rotation is 1 inch per 24 hours. Pretty slow, compared to the 1037 miles per hour at the equator.

Answer 3

Since the earth rotates once a day and it is roughly 24,000 miles around the equator. Any spot on the earth is traveling about 1,000 miles per hour or 1674 km/hour (This is approximately 465 m/sec .)

v=2pi R/24hours

Answer 4

To make one complete rotation in 24 hours, a point near the equator of the Earth must move at close to 1000 miles per hour (1600 km/hr). The speed gets less as you move north, but it's still a good clip throughout the United States.

Answer 5

the world turns on its invisble axis and at the same time it orbits the sun

Answer 6

The Earth rotates once per 24 hours and has a circumference at the equator of 24859.82 miles (40008 km). So at the equator it is moving at just a bit over 1000 mph.

Answer 7

900 miles per hour 1670 km/hr

you could try taking the circumference of the earth and dividing it by the increment of time you want your answer in (40,075.02 KM / 24) = 1669.7925 km/h

Answer 8

One rev per day.
