Physics often focuses on simplifying complex phenomena to better understand and predict the natural world. This art of idealization is a cornerstone of mechanics, where we frequently encounter the concept of a “particle” or “point mass.” Within this context, the moment of inertia plays a crucial role, particularly in rotational dynamics. In thermodynamic equilibrium, all…
