How fast would the Earth have to spin for us to feel it?

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.

Does the Earth spin so fast we can’t feel it?

Since the Earth rotates at a near-constant speed (that is, it doesn’t speed up or slow down in any way noticeable to us), we simply spin with it and don’t feel a thing. Well, we do feel the wind which is caused in part by the rotation of the Earth.

What would happen if the Earth spin 1 mph faster?

The faster the Earth spins, the shorter our days would become. With a 1 mph speed increase, the day would only get about a minute and a half shorter and our internal body clocks, which stick to a pretty strict 24-hour schedule, probably wouldn’t notice.

How fast would a planet of Earth’s mass and size have to spin so that an object at the Equator would be weightless give the period of rotation of the planet in minutes?

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.

Can astronauts see the Earth rotating?

From space stations, no. They are going around the Earth so quickly that the Earth will appear to be rotating backwards. Their own motion will mask the rotation of the Earth from casual observation. From the moon, not exactly, in the same way you can’t see the hour hand of a clock moving.

What if the Earth spun slower?

If the Earth gradually slowed, the bulging water from the oceans would begin to move away from the equator towards the poles. Once Earth stopped spinning completely, leaving it as a sphere, the oceans would flood most of Earth leaving one giant megacontinent around the middle of the planet.

What happens if the Earth spins backwards?

Short answer – the reversed spin would make the Earth much greener. Long answer – this new rotation would change winds and ocean currents, and that would shift the planet’s climate entirely. Instead, a different current would surface in the Pacific and become responsible to distributing heat around the globe.

How long would a day be if the Earth were rotating so fast that objects at the equator were apparently weightless?

So This will be called to around 85 minutes. This is the answer.

How fast is the Earth really moving?

Earth moves very fast. It spins (rotates) at a speed of about 1,000 miles (1600 kilometers) per hour and orbits around the Sun at a speed of about 67,000 miles (107,000 kilometers) per hour.

How many degrees does the Earth rotate in one hour?

The Earth rotates approximately 15 degrees in one hour. This is determined by dividing the number of degrees in one full rotation (360) by the number of hours in one day. Does Three Gorges Dam slow Earth’s rotation?

Which way does the Earth rotate and why?

The Earth spins because it formed in the accretion disk of a cloud of hydrogen that collapsed down from mutual gravity and needed to conserve its angular momentum. It continues to spin because of inertia.

How fast does the Earth spin in miles per hour?

In addition to the rotational speed of the Earth spinning on its axis, the planet is also speeding at about 66,660 miles per hour (107,278.87 km/h) in its revolution around the sun once every 365.2425 days.
