How fast the Earth would rotate so that particles at its equator fly off?

The Earth would have to spin once every 84 minutes to achieve that speed at the equator, or about 17 times faster than it actually spins. If you move away from the equator the centrifugal force is lower so you still wouldn’t fly off into space, even at that speed.

What would earth’s rotational period need to be in order for someone at the equator to experience a centripetal acceleration equal to G?

This means that the Earth would need to rotate with a period of 1 hour 24 minutes. This means it would need to rotate approx. 20 times faster than it does now!

What should the minimum angular speed of the earth be so that objects would fly off its surface?

To escape the gravity of earth from its surface, a body has to have at a minimum the known escape speed ve=11.2km/s in any direction away from the surface.

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

Is Earth’s rotation accelerating?

How quickly does Earth spin? Earth usually rotates about its axis bang on time, with one rotation taking exactly 86,400 seconds (1,440 minutes or 24 hours). As of 2020 the planet has stopped slowing down and is now speeding up. A day now lasts for half a millisecond less than 24 hours.

At what angular speed of earth the object on equator of earth will escape to infinity from its surface?

On the surface of the Earth, the escape velocity is about 11.2 km/s, which is approximately 33 times the speed of sound (Mach 33) and several times the muzzle velocity of a rifle bullet (up to 1.7 km/s).

Will happen if the Earth starts rotating at a faster speed?

At 100 mph faster, the equator would start to drown. If we double the speed at the equator, so that Earth spins 1,000 miles faster, “it would clearly be a disaster,” says Fraczek. The centrifugal force would pull hundreds of feet of water toward the Earth’s waistline.
