Minimum Speed for the Water to not spill

  1. Feb 28, 2012 #1
    How is it that the water in a bucket, spun fast enough, does not spill?
    The formula at the top would be Total Force = Tension + M*g right?
    So would the tension be let as 0? If so, why? I can't understand how the water just simply does not fall out of the bucket :confused:

    because the bucket is technically accelerating downwards just as fast as gravity is accelerating the water in the bucket (in otherwords, the bucket is keeping up with the water).
