Study Notes
Rigid Rotating Objects
- On a rigid rotating object, such as the Earth, different points do not move the same distance, but they rotate through the same angle.
- The rate of rotation is the same for all points on the object, meaning they complete one full cycle in the same amount of time.
- The rotation rate is independent of the radius or distance from the axis of rotation, which is why points closer to the axis move shorter distances while points farther away move longer distances.
- The angular displacement of all points is the same, resulting in a uniform rotation rate across the entire object.
