-you swing it quickly

-you swing it slowly

-you swing and stop it when it is directly overhead

1.What happened when you swing it quickly?

1.1Explain your observations using the concepts and math equations of UCM.

The centripetal acceleration creates a force that "pushes" the water toward the bottom of the bucket, or

$$mg=mv^2/r.$$
