Question

Which of the following exhibits rotational motion but not rectilinear motion?

• A. A drill that bores a piece of wood
• B. A spinning fan
• C. The rear wheel of a moving bicycle
• D. A ball rolling on a straight road

Answer 1

The correct option is B A spinning fan

A type of motion in which the body rotates about its own axis is known as rotational motion.

Rectilinear motion is the motion of an object moving in a straight line.

A ball rolling on a straight line undergoes both rotational and rectilinear motion.
Similarily, the drill and the rear wheel undergo both rotational and rectilinear motion.

But a spinning fan only rotates about its axis, it does not exhibit rectilinear motion.
