What is the formula for kinetic energy of rotating rigid body?

Posted in ROTATIONAL MOTION | Email This Post Email This Post |

The kinetic energy of the whole body is equal to the sum of the kinetic energy of all the particles present in the body. A rotating rigid body has kinetic energy because all atoms in the object are in motion.

The formula for kinetic energy of a rotating rigid body is given as,
Kinetic Energy (K.E.) = 1 /2 ( Moment of inertia (I) × (angular velocity)2)

kinetic energy of rotating rigid body

where  ω = angular velocity
