$\huge\bf\red{ꋬꋊꇙꅐꏂꋪ }$

Rotational kinetic energy can be expressed as: Erotational=12Iω2 E rotational = 1 2 I ω 2 where ω is the angular velocity and I is the moment of inertia around the axis of rotation. ... The instantaneous power of an angularly accelerating body is the torque times the angular velocity: P=τω P = τw
