Question
Select the correct statements:
  1. A simple harmonic motion is necessarily periodic.
  2. A simple harmonic motion is necessarily oscillatory.
  3. An oscillatory motion is necessarily periodic.
  4. A periodic motion is necessarily oscillatory.

Answer

  1. A simple harmonic motion is necessarily periodic.
  2. A simple harmonic motion is necessarily oscillatory.
Explanation:
A periodic motion need not be necessarily oscillatory.
For example: The moon revolving around the earth.
Also, an oscillatory motion need not be necessarily periodic.
For example: Damped harmonic motion.
