Chapter 21. Angular Momentum. Definitions. P = period in seconds (sec) f = frequency in Hertz (Hz or rev/sec) w = angular speed ( rad /sec) P=1/f w = 2 p f. I = Rotational Inertia.

Which axis of a book has the highest moment of inertia?
Note: “Minimum angular speed” means that FN=0.
You’d lose “weight”!
