Moment of Inertia

Definition

Moment of inertia measures an object's resistance to changes in its rotational motion. It depends on both the mass distribution and the axis of rotation.

Rotational Motion:

Rotational motion refers to the movement of an object around an axis or center point.

Angular Momentum: Angular momentum is a property of rotating objects that depends on both its moment of inertia and angular velocity.

Parallel Axis Theorem: The parallel axis theorem states that the moment of inertia about any axis parallel to an axis through the center of mass can be calculated by adding the moment of inertia about the center of mass and a term related to the distance between the two axes.
