Simple harmonic motion is a type of________________?
Correct answer: D. Vibratory motion
- A. Rotational motion
- B. Circular motion
- C. Musical arrangement
- D. Vibratory motion
Explanation
SHM is an oscillatory or vibratory motion in which the restoring acceleration is proportional to displacement and directed toward the mean position. A pendulum for small angular displacements and a mass-spring system are examples. The likely mistake is choosing b because circular motion can be used to model SHM, but SHM itself is classified as vibratory motion.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
