## Rotational Kinetic Energy : Definition, Formula, Units,

So, the rotational kinetic energy, \ (KE_R = \frac {1} {2} Iω^2\). Here \ (I\) is the rotational mass or moment of inertia of a rotating object, and \ (ω\) is the angular speed.

## Rotational Kinetic Energy

The object’s rotational kinetic energy is the sum of the kinetic energies of all the particles: K rot = (½) m 1 ω 2 r12 + (½) m 2 ω 2 r22 + .. = (½) (Σmr 2) ω 2 .. (1) Now, Σmr 2 is known as moment of inertia I, which is the
