Which one of the following has no significance with moment of inertia:

(A)M.I. is a reluctance to change its rotational state
(B)M.I. plays same role of mass in linear or translation motion
(C)M.I. gives inability of body to change its rotational state
(D)M.I. helps to accelerates the rotational motionCorrect

Answer: (D)

Solution

Moment of inertia is the opposition to change in the rotational state and plays the role of mass, as in
