How fast would the earth have to spin to counteract gravity? Or am I just a retard?

Question

And how badly would I throw up and die if we were spinning that fast?

Answer 1

The earth would have to spin fast enough so that centrifugal force outward was stronger than gravity inward. Since you're already "spinning" at about 1,030 miles per hour at the equator, you wouldn't throw up, and wouldn't notice it at all -- you only feel changes in velocity, if you're moving a constant velocity you don't feel like you're moving. Except for that centrifugal force thing.

At the equator the earth would have to be spinning at about 15,000 miles per second for centrifugal force to overcome gravity's pull. Trouble is, it wouldn't be just you that would go flying off into space, it would be *everything*, since gravity is what pulls earth together into a sphere. It would throw itself apart long before you got a ride into space :)

Answer 2

Retarded.

Gravity has to do with the attraction between any objects with mass. The fact that the earth is spinning has nothing to do with it.

On a barf scale of 1 to 10 (3 is where we are at now), it would be an 7 or 8 if we speed up the rotation and 0 to 1 if it slowed down.

Answer 3

I don't really know but I don't think the speed of rotation can effect gravity if it spins 1000 times faster...well if that ever happen, we all will probably be dead because we will be push out of the earth...the law of motion says that an object will continue to move unless acted upon by another force...since the gravity is weakened (gravity the force that stop us from moving) It can no longer stop us... after all this is just my hypothesis... I don't even know if you guys even understand what iam saying lol...Oh and if you didn't see the answer to the throw up part of your question, no you will not throw up, you will die instead =].

Answer 4

No you are not a retard.
I have never come a cross a reasonable explanation of gravity. I don't think anybody really knows what it is. But it can be measured, so, in theory, it should be possible to calculate the centrifugal force needed to overcome it it, but I'm not going to try.
I'd just say that its a hypothetical question, and the answer is 'very fast'

Answer 5

At a day length of around 1:25 (~1/17th of what it is now), centrifugal force at the equator would equal gravity and the Earth would start flying apart. Motion sickness would be the least of your problems.

Answer 6

I did a not elementary calculation and figured a a million,000 foot diameter wheel (the 2001 area station seems about that huge to me) might want to ought to do about 2 RPM (one rotation in 30 seconds) to make 1G. it quite is about how briskly it regarded in the movie. this isn't through coincidence. that they had technology experts to get as lifelike as accessible, and that i'm particular they calculated the perfect rotation cost and length and teach it that way in the movie on purpose. more suitable diameter can rotate slower. An 8,000 mile diameter area station might want to favor to make one rotation in ninety minutes. I %. 8,000 miles because it quite is Earth's diameter. If Earth rotated once in ninety minutes fairly of once in 24 hours, gadgets on the equator might want to be weightless.

Answer 7

the question should be we rotate once a day you can see that, so where can all this be generating speed, we are part of the milky way Galaxy and are traveling 34500 miles an hour through space as a part of it. do the math hm mm...I'll go for retarded and be happy we got gravity other wise we all would have to suck in order to retain our social pecking order

Answer 8

If everyone on earth began running against the rotation of the planet at the same time, would the day go faster?

Answer 9

Um, I'm leaning towards retard.

Answer 10

all the earth has to do is stop spinning and there will be no gravity.
