In physics, angular momentum is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity—the total angular momentum of a closed system remains constant. Angular momentum has both a direction and a magnitude, and both are conserved
According to Nother's theorem, there is a symmetry of rotation in space with implies that the angular momentum of a system will be conserved only if the symmetry of rotation in space is valid and vice versa is also true.
some people also call it the rotational analog of linear momentum but I avoid that.
mathematically for a rigid body, angular momentum is the product of the moment of inertial and angular velocity or I . w.
this conservation law is not only valid for the rigid system but for everywhere in space
angular momentum of the system is the summation of dm.v.distance from the axis.
