Solution
Correct Answer:
Axis and mass distribution
The moment of inertia (I) represents a body's resistance to rotational acceleration, analogous to mass in linear motion. I=∑miri2 where ri is the perpendicular distance of mass element mi from the axis of rotation.
- It depends on the total mass.
- It depends heavily on the distribution of mass (how far it is from the axis).
- It depends on the choice of axis (the same object has different I for different axes).
This easy difficulty physics question is from the chapter rotational motion, covering the topic of moment of inertia basics. It appeared in the 2025 exam.
