Ek=12Iω2E_k = \frac{1}{2}I\omega^2Ek=21Iω2
Mass (mmm)
Linear velocity (vvv)
v=rωv = r\omegav=rω
Device designed to store rotational kinetic energy
Proportional to ω2\omega^2ω2 (square of angular velocity)
Position mass far from axis of rotation
Linear KE + rotational KE
v=rωv = r\omegav=rω where vvv is linear, ω\omegaω is angular velocity
I=12mr2I = \frac{1}{2}mr^2I=21mr2
