1) When we use the equation of L=(moment of inertia)*(omega) to calculate the angular momentum of a rigid body rotating around a moving axis, why the axis of rotation must pass through the centre of mass of this body and the axis should also be a symmetrical axis?(adsbygoogle = window.adsbygoogle || []).push({});

2) If for a fixed and non-moving axis, is this necessary to pass through the centre of mass?

Pls help, thanks.
