🌀⚙️ One Rotation, Many Accelerations — How Motion Depends on Where You Are In rotational motion, not every part of an object experiences motion the same way. Even though gravity acts equally on the entire rigid body, different points can have different linear accelerations simply because they are at different distances from the axis of rotation. Here’s the key idea: All points in a rotating body share the same angular velocity (ω) and angular acceleration (α), but their linear quantities depend
