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

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).

oooh I get it :) thanks!
