Question

Which of the following statements is correct?
A. Every periodic motion is simple harmonic motion.
B. In simple harmonic motion the period is proportional to the square of the amplitude of oscillation.
C. In simple harmonic motion the phase constant depends on initial condition
D. The resonance frequency of a driven oscillator depends on the damping.

Answer 1

Correct Answer - C
All perriodic motion is not simple harmonic motion but all simple harmonic motion is periodic. Hence, option (a) is an incorrect statement. In SHM, the period is independent on the amplitude of oscillation. Hence, option 9b) is an incorrect statement.
In SHM, the phase constant is determined by the initial conditions.
Hence, option (c) is a correct statement.
the resonance frequency of a ddriven oscillator does not depend on the damping.
hence, option (d) is an incorrect statement.
