Moment of inertia is a measure of an object's resistance to changes in rotational motion. It is important because it helps us understand how objects move and behave when they are rotating.
The moment of inertia of an object is calculated by multiplying the mass of the object by the square of its distance from the axis of rotation.
The moment of inertia of an object is affected by its mass, shape, and distribution of mass. Objects with more mass or distributed mass farther from the axis of rotation will have a larger moment of inertia.
Moment of inertia calculation is used in many engineering and physics applications, such as designing machines and structures that rotate, analyzing the motion of rotating objects, and understanding the behavior of gyroscope and flywheel systems.
No, moment of inertia cannot be negative. It is always a positive value that represents an object's resistance to rotational motion.
