Oscillatory or vibratory motion can be defined as:
Correct answer: C. To and fro motion about the mean position
- A. Upward motion from mean position
- B. Right hand motion of the pendulum
- C. To and fro motion about the mean position
- D. Random movement of gas particles
Explanation
Option A : Upward motion from the mean position is not the definition of oscillatory motion.Option B : The right-hand motion of the Pendulum is not oscillatory.Option: C Oscillatory motion can be defined as to and fro movement about the mean position. Option D : Random movement about f gas particles is not oscillatory or 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.
