Minimum Speed for Water in a Bucket Revolving in a Vertical Circle

The video tutorial explores the problem of determining the minimum angular speed required to spin a bucket in a vertical circle without water spilling out. It begins with an introduction to the problem, followed by drawing a free body diagram to understand the forces involved. The tutorial then explains the concept of minimum speed and calculates the angular velocity needed. Finally, it clarifies the radius used in the calculations.

What is the relationship between the radius of curvature of the water's projectile motion and the radius of the circle through which the bucket is moving?

How does the force of tension change as the angular velocity decreases?

What is the significance of the variable R in this problem?
