  1. As inertia increases, does velocity always decrease? Is it that the increase in radius leads to and increase in the time it takes for a complete revolution?

  2. Moment of inertia is not the same as inertia....

    m~>mr^2
    Linear~>rotational analog
    Critical examples: collapsing star, figure skaters, and putting you hands out when you lose your balance...

    Check: what do tight rope walkers use to balance?

    WHY?

    ANS: a thin light pole with mass on the end it's like having a set of handle bars to.
