External Torque

Definition

External torque refers to the rotational force applied to an object by an external agent, causing it to rotate around a fixed axis. It is the net torque acting on an object due to forces external to the system.

Moment of Inertia:

Moment of inertia is a measure of an object's resistance to changes in its rotational motion. It depends on both mass distribution and shape.

Angular Acceleration:

Angular acceleration refers to how quickly an object's angular velocity changes over time. It is caused by applying a net torque on the object.

Conservation of Angular Momentum:

Conservation of angular momentum states that if no external torques act on a rotating system, then its total angular momentum remains constant.
