In rotational motion of a rigid body all particle move with
same linear and angular velocity
same linear and different angular velocity
with different linear velocities and same angular velocities
with different linear velocities and different angular velocities
As we have learned
Rotation -
A rigid body is said to be in pure rotation if every particle of the body moves in a circle and centre of all the circles lie on a straight line called the axis of rotation.
- wherein
The line joining any two internal points does not remain parallel.
In a rigid body
all particle rotate with same angular velocity but different linear velocities
r is different for all particles
