1. The problem statement, all variables and given/known data This is a general query not a specific problem. In several questions in rotational dynamics they ask the trend in angular acceleration and angular velocity.In one of them they released a rod from horizontal position and asked if the angular velocity and angular acceleration are increasing/decreasing In another one they release a square sheet but the trend is different. Is there a concrete and easy way to figure this out. have a very happy new year!!
