Which of the following is a periodic but NOT oscillatory motion?
AVibration of a guitar string
BPendulum bob swing
CSpring-mass oscillator
DMotion of the moon around the earth
Answer & Solution
Correct answer: D. Motion of the moon around the earth
1. Every oscillatory motion is periodic, but the converse is not true (5.2).
2. The moon orbits the earth on a circular/elliptical path — same set repeats but it is not to-and-fro.
3. Hence it is periodic but not oscillatory.
