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.

What can hold a greater volume of water than a mug?
a bucket...
Is bucket a noun?
Yes, bucket is a singular, common, concrete noun.
If you have a four gallon bucket and a nine gallon bucket of water how can you get 6 gallon in each?
can't get 6 gallons of water in a 4 gallon bucket
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.
Does an an egg cup or a can of pop or a bucket or a pint of milk have the largest volume?
If the bucket holds more than 16 fluid ounces, then the bucket is what you're looking for.
Why doesn't water in a bucket fall when it is vertically rotated?
Because the centripetal reaction force of the rotating bucket exceeds the force of gravity attempting to pull the water out.
Is it possible to rotate a bucket of milk in a vertical plane without spilling the milk?
Yes, in a centrifuge
Would a snail be able to get out of a full bucket of water?
Snails are able to climb vertical surfaces with ease.
What is the tension in a roper that is supporting a 4.2 kg bucket?
If the rope is hanging vertical ... one end from the ceiling and the other end to the bucket ... then the tension in the rope is 41.16 newtons (9.26 pounds).
What is The answer to level 75 ON fill The pot?
Bucket placement: 1-Place a bucket in the bottom left corner of the grid. 2-the next goes one row up and one column over so that the right end of the first bucket is covered 3-place a bucket directly above the second bucket in the fourth row from the top 4- place this bucket one row up and one column to the right of the 3rd bucket (this should cover the right end of the 3rd bucket) 5- place this bucket directly next to the vertical pipe on the right side 6- place in bottom right corner 7- place one row up and one column to the left of bucket #6 (this should leave the right end of bucket 6 uncovered) Pipe placement: 1-below the vertical pipes on the left side place a pipe that curves up and right 2- above the vertical pipes on the left side place a pipe that curves left and down 3- connect the horizontal pipe to the #2 pipe 4- to the right of the stationary horizontal pipe place a pipe that curves left and up 5- connect a pipe that curves up and left to the bottom of the vertical pipe on the right 6- to the top of the vertical pipe connect a pipe that curves right and down 7- connect a pipe that curves up and right to pipe #6
How do you connect a paint bucket to an air an air gun?
It depends on the airgun and bucket in question. The two you are using might not be compatible which would explain your confusion. I would check the instructions for the bucket and gun to see how they connect and if they are compatible.
How rotating the coil causes the lamp to light?
Well it is according to faraday's laws of electromagnetic induction. Whenever a coil rotates in a magnetic field,magnetic flux passing through the coil will get changed, and faradays first law states that whenever there is a change in magnetic flux linked with the coil, a emf is induced in it. So due to this emf bulb will light up. Well if you want the change in flux to be explained in more general way I can explain it like this: Suppose it is raining and you have kept a bucket to accumulate the rain water in it. Initially keep the bucket vertical, so maximum amount of rain water will drop into bucket. Now start tilting the bucket, the waterdrops entering the bucket will start decreasing. now make the bucket horizontal, so now no drop will enter into the bucket. So number of water drops entering the bucket depends on inclination of bucket. Here rainddrop is similar to magnetic flux and bucket is similar to coil. So as you rotate the coil, flux linked with the coil changes.
Name the forces acting on a plastic bucket containing water held above the ground level in your handdiscuss why the forces acting on the bucket do not bring change in its state of motion?
If it is held stationary, there will be the downward force of gravity, and the upward (normal) force from your hand. The reason that the bucket does not move is because the forces are equal and opposite.
How do I access other user buckets?

Is there any way to move or remove water on minecraft?
To make a bucket with iron ingots (link included to make one its hard to explain)
How do spin dryer dry clothes?
Basically the clothing is rotated in a ventilated bucket into which hot air is blown.... NO not true- a spin drier works by using a centrifugal action - that is as clothes spin at high speed the water in them is forced outward into the drum.
How many militers are in a bucket?
There is no standard size of bucket; the number of millilitres which fit in a given bucket vary from bucket to bucket.
