Physics question help?
Acquire a metal coat hanger for which you have permission to destroy. Pull the coat hanger apart. Using duct tape, attach two tennis balls to opposite ends of the coat hanger as shown in the diagram at the right. Bend the hanger so that there is a flat part which balances on the head of a person. The ends of the hanger with the tennis balls should hang low (below the balancing point). Place the hanger on your head and balance it. Then quickly spin in a circle. What do the tennis balls do?
Please explain why it would do what you say it would do.
btw, this is not my hw....i found this question online, and i'm studying for a physics test and trying to understand the concept. as hard as it may be for some ppl to believe.

The tennis balls would spin, as the force of gravity is relational to the speed of which you are spinning. You are creating no resisting force, so they will follow, but in different directions, as one is closer to the centre of gravity

Well.. the balls should stay nearly still because there is not enough surface area and therefore friction to cause the coat hanger to spin with your head.
