Moment of inertia is a physical property of an object that measures its resistance to rotational motion. It is a quantitative measure of how difficult it is to change an object's rotational velocity.
Moment of inertia is a crucial factor in rotational kinematics, as it determines the amount of torque required to produce a given angular acceleration. In other words, it is directly related to an object's rotational motion.
The moment of inertia of an object can be calculated by multiplying the mass of the object by the square of its distance from the axis of rotation. It is also affected by the shape and distribution of mass within the object.
The unit of measurement for moment of inertia depends on the system of units being used. In the SI system, it is measured in kilograms per square meter (kg•m²). In the imperial system, it is measured in slug•ft².
Mass is a measure of an object's resistance to linear motion, while moment of inertia is a measure of its resistance to rotational motion. In other words, they are two different physical properties that describe an object's behavior in different types of motion.
