किसी घूमते हुए पिंड की घूर्णी गतिज ऊर्जा किस अभिव्यक्ति द्वारा दी जाती है?

A
(1/2)Iω²
B
Iω
C
(1/2)mv²
(1/2)एमवी²
D
mgh
एमजीएच

Explanation

This is the standard expression for the rotational kinetic energy of a body rotating with angular velocity ω\omega and moment of inertia II. It is analogous to the linear kinetic energy formula 12mv2\frac{1}{2}mv^2.
