A bucket containing water is rotated in a vertical circle. Explain why water does not fall?

Solution

Explanation:
When a bucket containing water rotates vertically in a circular path, then a centripetal force produces on it. Which is directed along the center of the circular path.
This centripetal force is $\frac{m v^{2}}{r}$ , where m is the mass of the system, v and r are the velocity and radius of the circular path.
The mass of the bucket water or the weight (gravitational pull) provides the necessary centripetal force to the rotation.
When we revolve the bucket in a circular path with our hand, we give an outward force on the bucket.
This outward force balances the gravitational force acting on the bucket water, that's why water does not fall from the bucket.
