How fast does something have to spin to create gravity?

To generate a force equal to one ‘g’, the station would have to spin sufficiently quickly to cause an acceleration of 9.8ms^-2. 0.31 rad/s ~ 2.96 RPM. This may seem slow, but don’t forget that I set the radius equal to 100m.

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

That means the day would last about 1.41 hours, or 85 minutes. However, such a rotational velocity would exceed the tensile strength limits of the Earth. This would destroy the Earth, of course. So being weightless would be the very least of your concerns in such a situation.

What will happen if Earth rotates 30 times faster?

An increase in Earth’s rotational speed could have various impacts on life, ranging from increased earthquakes and tsunamis to a shortening of the length of the day. People could be floating in central Africa while the polar ice might melt extremely fast, submerging most parts of the world.

How fast does the ISS spin?

The ISS revolves around the Earth at about 17,500 mph (~28,000 km/h) resulting in it completing one revolution in about 90 minutes, and about 16 revolutions per day. The ISS rotates about its center of mass at a rate of about 4 degrees per minute so that it will complete a full rotation once per orbit.

How fast would you have to spin in space to simulate gravity?

They envisioned a rotating wheel with a diameter of 76 meters (250 feet). The 3-deck wheel would revolve at 3 RPM to provide artificial one-third gravity. It was envisaged as having a crew of 80.

How fast would Earth have to spin 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.

How long would a day be if the earth were rotating so fast?

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. But if we were rotating 100 mph faster than usual, a day would be about 22 hours long.

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

How fast would Earth need to spin for those at the equator to have zero apparent weight?

The strength of the centrifugal force depends on where you are. It is greatest at the equator and zero at the Earth’s poles. We can calculate how fast the Earth would need to spin to balance the force of gravity (this is known as the ‘escape velocity’). It works out at about 28,437km/h (17,670mph).

How fast does the Earth have to rotate to cancel gravity?

The period of rotation of the Earth is about 24 hours (86 400 s). At that rate of rotation, the effect of spin is negligible. So how fast would it have to rotate to cancel gravity (at the equator)?

What is the speed due to the Earth’s rotation?

Solve for v. That would be about 60 million m/s which is about 37,000 miles/s or about 130 million miles/hour. By comparison, your actual speed due to the rotation of the Earth is far smaller, about 400 m/s. As you can see, then, the effect of the Earth’s rotation is pretty small compared to gravity.

Does the Earth’s spin affect its gravity?

Indeed the spin of the earth counteracts gravity for objects at the surface. At its present rate of rotation the effect is a few parts per thousand, and its direction and magnitude depends on latitude. The effect is greatest at the equator.

How long would it take to travel around the Earth?

This results in a minimum T of 5060 s, or 1.4 hours. Any faster than that, and not only do we fly off the surface, but the surface flies off the surface, and the planet itself breaks apart. Indeed the spin of the earth counteracts gravity for objects at the surface.
