Definition:

A rigid body performs a real rotational motion if each particle of the body moves in a circle, and the center of all circles lies on the straight line (axis of rotation).

As shown in the figure disc is performing rotational motion as all particles are rotating about a common axis i.e. axis of rotation.

Examples:

1. Rotation of ceiling fan.

2. Rotation of blades of a windmill.

3. Rotation of wheels of a car.
