Angular Momentum in Case of Rotation: Angular momentum is a property of a rotating object that describes its tendency to keep rotating. In the case of rotation, angular momentum is given by the product of the moment of inertia and the angular velocity of the object. The moment of inertia is a measure of how difficult it is to change the rotational motion of an object. It depends on the mass distribution of the object and the axis of rotation. The larger the moment of inertia, the more difficult it is to change the object’s rotational motion.

Angular momentum is a conserved quantity in the absence of external torques. This means that if no external torques act on a rotating object, its angular momentum remains constant. If external torques act on the object, the angular momentum will change, and the object’s rotational motion will be affected. This principle is known as the law of conservation of angular momentum.

Angular Momentum in Case of Rotation

The angular velocity is the rate at which the object is rotating. It is usually measured in radians per second.

The formula for angular momentum in case of rotation is:

L = Iω

Where,

• L is the angular momentum
• I is the moment of inertia
• ω is the angular velocity
