Moment of inertia is the ratio of:
Correct answer: D. angular momentum and omega
- A. mass and velocity
- B. momentum and omega
- C. momentum and acceleration
- D. angular momentum and omega
Explanation
The moment of inertia (I) is defined as the ratio of angular momentum (L) to angular velocity (ω), mathematically expressed as I=L/ω . Angular momentum is the product of mass, linear velocity, and the perpendicular distance from the axis of rotation (L = mvr), and ω represents angular velocity.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
