Question

State and prove law of conservation of angular momentum.

Answer 1

Explanation:

Principle of conservation of angular momentum states that, If no external torque acts on a system, the total angular momentum of the system remains constant. If I be the moment of inertia of a body about a given axis of rotation and w be its angular velocity, then I w = constant.

HOPE IT HELPS

Answer 2

The quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity.

Law:-

Principle of conservation of angular momentum states that, If no external torque acts on a system, the total angular momentum of the system remains constant. If I be the moment of inertia of a body about a given axis of rotation and w be its angular velocity, then I w = constant.

the proof in the attatched picture.. please mark me as the brainliest answer ....most welcome bro <3
