Question

In linear motion, the energy is given by 1 ⁄2mv² . Similarly, in rotational motion, the rotational energy is given by 

A. 1/2 × I × ω; where I: moment of inertia of the body, ω: angular velocity 

B. 1/2 × I² × ω; where I: moment of inertia of the body, ω: angular velocity 

C. 1/2 × I × ω²; where I: moment of inertia of the body, ω: angular velocity 

D. 1/2 × I² × ω²; where I: moment of inertia of the body, ω: angular velocity

Answer 1

C. 1/2 × I × ω²; where I: moment of inertia of the body, ω: angular velocity
