How fast would the Earth have to spin for us to fly off?

28,437 kilometres per hour
Gravity and the centrifugal force of Earth’s spin keep us grounded. In order for us to feel weightless, the centrifugal force would need to be ramped up. At the equator, Earth would need to spin at 28,437 kilometres per hour for us to be lifted off into space.

How fast does NASA say the Earth is spinning?

1670 kilometers/hour
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).

Does the Earth Spin 1000 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.

How fast are we spinning on your axis?

Earth spins on its axis once in every 24-hour day. At Earth’s equator, the speed of Earth’s spin is about 1,000 miles per hour (1,600 km per hour).

How fast would Earth need to rotate so the apparent weight at the equator is 0 n?

According to wikipedia the effective strength of gravity at Earth’s equator is ge=9.780m/s2, and where the radius is r=6378km. The rotation rate is ω0=7.292×10−5rad/s. Using the above figures we get ω1ω0≈17. The Earth would have to spin 17 times faster before people at the Equator became weightless.

What are some interesting facts about the Space Needle in Seattle?

Interesting facts about the Space Needle. The 1962 World’s Fair drew over 2.3 million visitors, when nearly 20,000 people a day used its elevators. The Space Needle has an observation deck at 160 meters (520 feet) and the rotating SkyCity restaurant at 150 meters (500 feet). The space needle observation deck,…

How long does it take to go up the Space Needle?

Visitors can reach the top of the Space Needle by three elevators that travel at 4.5 meters per second (10 miles per hour). The trip takes 41 seconds. On windy days, the elevators slow to 5 miles per hour (2.2 m/s). Each elevator carries 25 people.

How many people visit the Space Needle each year?

The Space Needle annually hosts more than 1 million visitors, making it the #1 tourist attraction in the Northwest. Being a major symbol of the Pacific Northwest, the Space Needle has made numerous appearances in films, TV shows and other works of fiction.

How many stairs are in the Space Needle?

Each elevator carries 25 people. The main stairwell has 848 steps from the basement to the top of the observation deck. 25 lightning rods (24 actual rods, plus the tower) are on the roof of the Needle to withstand lightning strikes.
