Rotational Inertia

Definition

Rotational inertia, also known as moment of inertia, is a measure of an object's resistance to changes in its rotational motion. It depends on both the mass and distribution of mass around the axis of rotation.

Torque:

Torque is the measure of how effectively a force can cause an object to rotate. It depends on both the magnitude and direction of the force applied.

Angular momentum:

Angular momentum is a property that describes an object's tendency to keep rotating at a constant rate. It depends on both rotational inertia and angular velocity.

Center of mass:

The center of mass is the point where all the mass of an object can be considered to be concentrated. It plays a crucial role in determining an object's rotational behavior.
