In the translational motion, we studied about the momentum of
Let us first discuss the basics of angular momentum and its calculation in different cases.
See the video below for the same.
We also studied about the law of conservation of Linear Momentum of a system, which states that total linear momentum of a system remains conserved if no external force is acting on the system. Similarly, we state Law of Conservation of Angular Momentum of a rotating body in which we consider, the absence of external torques on the rotating body its total angular momentum remain conserved. See the video below for understanding the Law of conservation of angular momentum.
There are many situations of rotational motion on which variety of problems are framed which involve the concept of Angular Momentum and its conservation.
To understand the applications of the concept see the example videos below.
