How does spin create gravity?
I understand the bucket of water example, but in space etc there is no bucket.
So where does gravity come from?
Answers:
gravity is th eforce of attractio between two things dependant on their mass and distance apart
a spinning bucket of water is experiencing centrefugal force not gravity
It's mass, not spin.
No, mass creates gravity.
You are describing centrifugal / centripetal forces with the bucket of water example.
its a mix of air and speend or somthin
No, mass creates gravity.

it's the centrifugal force that spin creates, i.e. it pushes everything to the outside, thats why the water stays in the bucket.
Gravity is not created by spin, nor is it created by anything other than matter itself. It is an inherent quality of matter. Gravity is a force of attraction between two objects, no matter how big or small. Now, if you are into math and physics, read about string theory and gravity, this will give you an idea of gravity's properties, it's possible causes, and its strength.
see this is what I was asking!! They explained that gravity does come from spinning! I don't understand this and personally, I don't think that the scientist fully understand this either,.
there I said it!
Good question!!!!
Spin doesn't create gravity - and it isn't gravity that keeps the water in the bucket, that's inertia and can be explained by Newton's laws of motion. Planetary and stellar orbits are a result of gravity, not the cause. Nobody really knows where gravity comes from, or why it exists, it's a very strange force and not much is understood about it. Most of what we know about it is empirical.
ps - there's no such thing as 'centrifugal force'. Again just Newton's laws of motion.
g force
Spin (rotational force) does not create gravity craig. Gravity pulls the objects around it towards its middle.
Spin can also, called centrefugal force, is the exact opposite of gravity. Gravity pulls, Spin pushes
I think you are confusing the effects of spin with centripetal acceleration; it is similar to the effects of gravity, but a different phenomena.
It doesn't really create gravity, it simulates the acceleration of gravity with centrifugal force.
Spin creates a fictitious force called centrifugal force. If you are in deep space, and your spacecraft is under spin, just like we can see in some movies, your body will feel a force that acts like a kind of weight. So, you'll feel like if you were under action of a gravitational field.
gravity is the term used to describe the attraction between two or more objects. You and your desk are attracted to each other, however the energy of that attraction is so small it is immeasurable. So in terms of gravity it only practical when talking about heavenly bodies (large bodies in space). Since the earth is large it has a measurable attraction force and we stick to it, like a small meteor passing by pulled into our atmosphere. We impose a force on the earth as well but it is so small that the earth is not attracted to us.
The spin of the earth does not create gravity. Even large "spinless" objects have a form of gravity, it is gravity is based on their mass and density (why no one really knows but it happens) - larger objects have a stronger gravity than smaller - such as the moon has less gravity than the earth (1/6 I believe) The rotation of the earth is 27x faster than that of the moon but gravity is not 27x greater. The earth is 6x larger that the moon and has 6x more gravity. (all numbers approximate)
However you can fake gravity in a weightless environment by inducing spin in a space craft. The spacecraft could rotate so that anything inside will be forced toward the outside by centrifugal force. this would mimic gravity, however gravity would be stable only if you stood still, if you walked in the opposite direction to the spin (into the spin) you can essentially increase the centrifugal force upon you body and then hence increase the "gravity" feeling, like wise if you walked in the direction of the spin (slowing the spin - relativity to your self) the "gravity" would be less.
Maybe you are think of this concept that is being looked at for long space voyages and possible space colonization.
gravity is a relationship really, between objects with have mass. Water spinning in a pail is responding to force, but not the same force as gravity.
Anything spinning around a point is accelerating towards that point. You, on the otherhand, would want to repel that force and fly away from that point. It is the combination of the two forces that re-creates the sensation of gravity.
Spin creates centrifugal foce around a fixed point on a radial axis, but does not work with anything spherical, because there would be no outward rotational force on the poles of the object (or planet), where the spin force is being applied.
Mass is what generates gravity.
From the big bang, planets began to form from heavy molecules binding to lighter ones; such as uranium bonding to zinc.
You also need to know that, at such a small scale, you didn't need a very large body to have a gravitational force, because there were no planets at the time.
However, back to your question.
You could have a object generate enough force to cancel out and overcome gravity, but a driving force would have to be applied.
The spinning motion inside the planet's core does not generate the gravity that holds it together (which is where you're probably confused) but provides the electromagnetic field around the earth which is just as vital.
The best answer any one can come up with is Buggered if i know
Gravity results due to the mass of an object.
F = GMm/r^2
where
F = force,
G = Gravitation constant,
M = mass of one object (e.g. Earth),
m = mass of another object (e.g. the Moon) and
r = distance between the two objects.
In the case of the bucket, centripetal force is created due to the spin and the tangential velocity makes it seem as if a centrifugal force exists.
