Question
Select the incorrect statement(s) from the following.
I. A simple harmonic motion is necessarily periodic.
II. A simple harmonic motion may be oscillatory
III. An oscillatory motion is necessarily periodic
- I only
- I and II
- II and III
- I and III
Hint:
Simple harmonic motion is a type of oscillatory motion
The correct answer is: II and III
All the Simple Harmonic Motions are oscillatory and also periodic, but not all oscillatory motions are SHM. Oscillatory motion is also called the harmonic motion of all the oscillatory motions, wherein the most important one is simple harmonic motion.
