SUMMARY
Angular momentum conservation applies to systems where no external torque acts on them. In the context of a rod struck by a ball, angular momentum can be conserved about the center of mass or any point along the base of the rod. However, if external forces or torques are introduced, such as friction or an external push, conservation principles may not hold. Understanding the specific conditions under which angular momentum conservation is valid is crucial for solving related physics problems.
