Question

Which of the following motion is not exhibited by any part of a rotating fan?

• A. Circular motion.
• B. Rotatory motion.
• C. Periodic motion.
• D. Linear motion.

Answer 1

The correct option is D Linear motion.

The fan rotates about a fixed axis hence it exhibits rotatory motion. The blades of the fan describe the circular motion. During the rotation, the different particles repeat their motion about a certain point, in a fixed interval of time, exhibiting periodic motion. But since it does not move in a straight line, it does not exhibit linear motion
