What is the speed of Earth?
roughly 1,000 miles per hour
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour.
Who figured out how fast the Earth spins?
February 3, 1851: Léon Foucault demonstrates that Earth rotates. By the mid 19th century, most educated people knew that Earth spins on its axis, completing a rotation once a day, but there was no obvious visual demonstration of the Earth’s rotation, only astronomical evidence.
How fast does the earth travel in 1 minute?
Explanation: 27.7 kilomers per minute at equator.
What is the speed of the Earth’s rotation?
What is the speed of the Earth’s rotation? At the equator, the circumference of the Earth is 40,070 kilometers, and the day is 24 hours long so the speed is 1670 kilometers/hour ( 1037 miles/hr). This decreases by the cosine of your latitude so that at a latitude of 45 degrees, cos(45) = .707 and the speed is .707 x 1670 = 1180 kilometers/hr.
How many miles per hour does the Earth travel in one year?
So in one year, Earth travels about 584 million miles (940 million km). Since speed is equal to the distance traveled over the time taken, Earth’s speed is calculated by dividing 584 million miles (940 million km) by 365.25 days and dividing that result by 24 hours to get miles per hour or km per hour.
What is the speed of a human moving at the equator?
This produces a speed at the equator of about 1,037 mph (1,670 km/h). You won’t be moving quite as fast at other latitudes, however. If we move halfway up the globe to 45 degrees in latitude (either north or south), you calculate the speed by using the cosine (a trigonometric function) of the latitude.
How do you calculate the speed of rotation at 45 degrees north?
To determine the speed at any other latitude, simply multiply the cosine of the degree latitude times the speed of 1,037.5646. Thus, at 45 degrees north, the cosine is.7071068, so multiply.7071068 times 1,037.5464, and the speed of the rotation is 733.65611 miles per hour (1,180.7 km/h). For other latitudes the speed is:
