Water in the Bucket: Free Body Diagram?? (Vertical Centripetal Force) 1. The problem statement, all variables and given/known data If a bucket tied to a rope is revolving vertically in an counter clockwise direction, what would be the Free Body Diagram of "water" in the bucket at the top position? 2. Relevant equations There are no equations 3. The attempt at a solution I am guessing there would be two forces: gravitational pointing downward and contact force with the bucket pointing in the direction opposite to the motion of the bucket so that would be left if the bucket is going counter clockwise vertically. Are there any more forces on water inside the bucket at the top position and am I right about the direction of the two forces.
