Some problems solved using angular momentum may involve a person or object changing shape to alter their/its moment of inertia. In this case, the person or object will often be idealized twice, as two different rigid bodies (the "before configuration" and the "after configuration"). This is permissible because a conservation process does not require detailed information about the intermediate stages where the person or object is actually changing shape. |
