Question

Which among the following is/are oscillatory motion?

• A. Bullet fired from gun.
• B. Clock pendulum.
• C. Motion of blades of a ceiling fan.
• D. Motion of a vibrating sitar string.

Answer 1

Answer: (B), (D)

The correct options are
B Clock pendulum.
D Motion of a vibrating sitar string.

If the body is in to and fro motion along the same path, it is called an oscillatory motion. Motion of clock pendulum and vibrating sitar string is oscillatory in nature.
Motion of blades of a ceiling fan is an example of rotatory motion and bullet fired from gun is an example of translatory motion.
