3. Desenibe the relation of the betweenmoment of inertia and kinetic energyofanobject. |

Answer» Answer: K = 1 2 I ω 2 . We see from this EQUATION that the kinetic energy of a ROTATING rigid body is directly proportional to the moment of inertia and the square of the ANGULAR VELOCITY. This is exploited in flywheel energy-storage devices, which are designed to STORE large amounts of rotational kinetic energy. |
