Spinning objects store kinetic energy proportional to their moment of inertia and the square of spin rate.
The math behind it
KE = ½·I·ω², the rotational analog of ½mv².
Worked Example
I = 3 kg·m², ω = 6 rad/s → 54 J.
Frequently Asked Questions
How is I found?
It depends on shape and mass distribution; use a moment of inertia calculator.
