SUMMARY
The angular momentum of a rigid body can be analyzed in both inertial and body coordinate systems. In the body system, where the rigid body is at rest, it can still possess non-zero angular momentum due to its rotational motion about its center of mass. This center of mass is defined as being at the origin (0,0,0) in the body system, which is distinct from the body's rotation itself. Understanding this distinction is crucial for accurately calculating angular momentum in various contexts.
