Which of the following correctly compares moment of inertia with mass in linear dynamics?.
- A.Moment of inertia is the rotational equivalent of mass.
- B.Moment of inertia is independent of mass.
- C.Moment of inertia is always less than mass.
- D.Moment of inertia has no relation to linear dynamics.
Model answer
What a good answer should say
- Moment of inertia is the rotational equivalent of mass.
Explanation
Why this works
Moment of inertia serves as the rotational counterpart to mass in linear dynamics, determining how an object resists angular acceleration, similar to how mass resists linear acceleration.
