I assume you mean when the bucket is spinning, so I will answer as such:
If a bucket spins at a sufficient speed, with a sufficient radius, then it will generate a centrifugal force (in reality there is no such thing, but mathematically we can use it to describe the force acting on the bucket and its contents) strong enough to overcome gravity.
Centrifugal force is described as follows:
Fc = mv^2/r
where Fc is the force pushing the water inside of the bucket, m is the mass of the water (that's the only thing we care about right now--I'll explain why later), v is the velocity, and r is the radius you're swinging the bucket about.
Now, the water won't fall out if and only if...
Fc ≥ Fg
where Fg = the force of gravity trying to pull it out of the bucket.
So really, we'd have...
mv^2/r ≥ (9.8)(m)
And here's why the mass doesn't matter: it cancels out! Simplify the equation on both ends to reach:
v^2/r ≥ 9.8
now, 9.8 is an ACCELERATION: it's 9.8m/s^2
To find out whether or not the water falls out of the bucket, fill in the velocity (tangential, not angular: that is, if you "let the bucket go" at any point, v= the speed it would fly away from you) and the radius you're spinning it about. If, when you perform this operation, you result in a number larger than 9.8 meters per second squared, the water stays in the bucket!
What else can I help you with?
Why doesn't water in a bucket fall when it is vertically rotated?
The water doesn't fall out of a vertically rotating bucket due to inertia and centripetal force. The inertia of the water causes it to continue moving in a straight line while the bucket moves around it, and the centripetal force generated by the bucket's motion keeps the water contained within the bucket.
Why can you not lift a bucket of water without holding it?
You cannot lift a bucket of water without holding it because you need to apply a force to overcome the weight of the bucket and the water inside it. If you do not hold it, the force of gravity will cause it to fall back down. Holding the bucket allows you to apply the necessary force to lift it.
Why cant you lift a bucket of water without holding it?
Because if you Don't, you will fart. Jon
If you shoot a gun in a bucket of water will the bucket bust?
No, the bucket will not bust if you shoot a gun into a bucket of water. Water is a dense material that absorbs the impact of a bullet, preventing the bucket from breaking. However, the force of the shot may cause the water to splash out of the bucket.
Why does water in a bucket not fall out when it spins around?
it happens because the air pressure counteracts the gravitational pull of the water which allows the water to stay in the bucket centrifugal acceleration and gravitational acceleration are indistinguishable from each other despite the fact that they arise from different causes. Therefore if v2/r > Gm/r2 then the water will obey the centrifugal acceleration over the gravitational. sorry, but the guy talking about air pressure is incorrect. the force pushing the water up from centripital force is greater than that of gravity, therefore it will not fall out.

What would happen to water if you stopped the motion of the bucket upside down?
If you stop the motion of the bucket upside down, the water inside the bucket will continue to move in the direction it was going due to its inertia. This means that the water will temporarily remain in place inside the bucket while the bucket comes to a stop, before eventually falling due to gravity.

Pour a bucket of water.
How do you get a bucket of water on runescape?
get a bucket, go to a fountain or an other water spot, click on use bucket and click on the water.
Have you ever drawn water from a well and felt that the bucket of water is heavier when it is out of the water?
No, I haven't. But, when the bucket is in the water, the weight is supported by the water in the well. Once the bucket is raised out of the water, the weight is no longer supported, and the full weight of the bucket and the water within the bucket is felt as it is raised towards the surface.

No, the bucket will not bust if you shoot a gun into a bucket of water. Water is a dense material that absorbs the impact of a bullet, preventing the bucket from breaking. However, the force of the shot may cause the water to splash out of the bucket.
Would you cool a bucket of water faster by putting ice into water or a bucket of water into ice?
You would cool a bucket by putting ice into the water.
If a bag of 3 percent salt water is placed into a bucket of 0.3 percent salt water then the solution in the bucket is what compared to the solution in the bag?
The salt solution in the bucket is 10% of the salt solution in the bag. The bagged solution has a higher density than the bucket solution; therefore, the bagged solution will most likely fall to the bottom of the bucket as the bucket water is displaced above it -- assuming there is no air in the bag, the density of the bag material is negligible, and the salt is fully dissolved in the water. Details: = The solution in the bucket is 0.3% while the solution is the bag is 3%. Thus, the solution in the bucket has less concentration of salt than the solution in the bag. Hence, the solution in the bucket is hypotonic to the solution in the bag.
About how much water does a bucket hold?
It depends on the bucket size, but usually a standard size bucket would hold a few litters of water.
