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.

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 doesn't water fall out of a bucket?

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!


How far can you fall into water and still survive?

The height from which a person can fall into water and still survive depends on various factors such as the angle of entry, the speed of the fall, and the depth of the water. Generally, a fall from a height of around 50 feet or less into deep enough water can be survivable if the person enters the water correctly and does not hit any obstacles. However, falls from greater heights can result in serious injuries or fatalities. It is important to always exercise caution and be aware of the risks when jumping or diving into water from any height.

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.


Why doesn't water fall out of a bucket when it is swung quickly?

Water doesn't come out of the bucket while spinning it rapidly because of contrifugal force, it makes things move away from the center. Try spinning around for 7 secs and move your hands, it will feel hard to move down cause of contrifugal force.

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.

What keeps water in a rotating bucket from falling out?

Centripetal force. The water wants to fall out due to gravity, but the speed of the rotating bucket cancels it out, creating an inward acceleration.. It is the same as why you don't fall out of an upside sown roller coaster. The speed has to such to cancel out gravity acceleration, where velocity squared divided by the radius of the rotating circle is the acceleration of gravity


Will colder night temperatures and warm days cause significant evaporation over a week or would you consider that a leak issue?

Evaporation rates vary with weather conditions. The BEST way to simply determine whether the pool has a leak is called the 'bucket test'. 1) Partially fill a bucket with the pool water and mark or measure the water level in the bucket. 2) mark or measure the water level in the pool(does not have to be the same level as water in bucket) 3)Place the bucket on the top step of the pool and leave for 24 hours (or for as long as you like, but sufficiently long to see a change in water level due to evaporation). The fall in the two water levels, pool and bucket, should be exactly the same (eg: 0.5" drop in pool waterlevel and 0.5" drop in bucket water level). If the water level in the pool has fallen further than has the water level in the bucket, the pool has a leak.

Why water does not fall If a bucket containing water is rotated in a vertical circle. Explain.?

Newton's thrid law states that for an action, there is an equal and opposite reaction, in an inertial reference frame. The bucket at the highest point experiences two types of acceleration. One is gravity pointing downwards. Another is centripetal acceleration, which deters it from moving either to the right or to the left. The centripetal acceleration also points downwards. The bucket, at zero vertical velocity, applies a force on the water, equal to the centripetal force yet inthe reverse direction. Therefore, the water in the bucket feel zero instantaneous force at zero instantaneous velocity. According to newton's first law, it shouldn't fall at that point.
