    Verified Answer
    The expression Iω2/2 represents Rotational ____________a)Kinetic...
    CONCEPT:
    • Rotational kinetic energy: The energy, which a body has by virtue of its rotational motion, is called rotational kinetic energy.
    • A body rotating about a fixed axis possesses kinetic energy because its constituent particles are in motion, even though the body as a whole remains in place.
    • Mathematically rotational kinetic energy can be written as -
    Where I = moment of inertia and ω = angular velocity.
    EXPLANATION:
    • From above it is clear that,  represents rotational kinetic energy.
