Measuring Angular Momentum
How would I go about solving the following problem: If
you put a marble inside of a balloon, inflate it, and tie it, start
spinning the marble around the balloon, how do I measure the various
amounts of angular momentum inside of the balloon? i.e., As the marble
starts to fall back down to its original state, how does the velocity
increase, and how does that effect how quickly the marble will fall back
down to its original state?
A lot depends on whether the balloon is held stationary or is part of
the problem. Generally, the problem is too complicated to answer other
than in very general terms (e.g., conservation of energy) or very
specific terms (the equations of motion of the marble-balloon system,
including friction, elasticity, etc.).
