key term - Angular Momentum

Definition

Angular Momentum is the measure of how much rotational motion an object has, calculated as the product of its moment of inertia and angular velocity.

Related terms

Moment of Inertia: The resistance of an object to changes in its rotational motion, depending on its mass distribution and shape.

Torque:

The measure of how effectively a force can cause an object to rotate, calculated as the product of force and lever arm distance.

Conservation of Angular Momentum: The principle that states that the total angular momentum of a system remains constant if no external torques act on it.
