Angular Kinetic Energy = 1/2 I \omega^2
Angular Momentum \vec "L" <-> Moment of Inertia "I"
L_(reference point) ... not intrinsic proprety unilke linear momentum
not universally conserved
\vec{F} = \frac{d\vec{p}}{d t}
\vec{L_Q} = \vec{r_Q} \crosss \vec{F} <- \vec\tau_{Q,external} <- torque
"spin angular momentum" intrinsic property indepent of reference point ["spin" <-> rotation about its center of mass]
Only 3 star fates "white dwarf" | "neutron star" | "black hole"
super nova not star, but the outcome of a neutron star formation.
