# Reopen the «How is angular momentum measured in experiments/in practice?» topic

Moderators @Qmechanic and @dmckee marked it as a duplicate, but it is not so (see How is angular momentum measured in experiments/in practice? ). Linked questions are restricted to fundamental particles, whereas angular momentum is a concept applicable to any system. I now can’t post an answer about composite particles (currently at How does one experimentally determine chirality, helicity, spin and angular momentum of a fundamental particle? ) into correct thread.
