Which of the following is true about the rotation of a rigid object?
Which of the following is true about the rotation of a rigid object?
- The rotation of the object is dependent on the material it is made of
- The rotation of the object is dependent on the axis of rotation

Study Notes
Rigid Object Rotation
- A common characteristic of the rotation of different points on a rigid object is that they rotate at the same rate.
- When a rigid object rotates about a fixed axis, the rotation rate of different points on the object remains the same.
- The reason why different points on a rigid object rotate at the same rate is that they are connected and move together as a single unit.
- The statement that is false about the rotation of a rigid object is that different points on the object rotate at different rates.
