1.	Which of the examples represent simple harmonic motion and which represent periodic but not simple harmonic motion ? General vibrations of a polyatomic molecule about its equilibrium position.
Answer» SOLUTION :It is a periodic but not S.H.M. A POLYATOMIC gas MOLECULE has a number of NATURAL frequencies and its GENERAL motion is the resultant of S.H.Ms. of a number of different frequencies. The resultant motion is periodic but not S.H.M.
