The angular frequency ω of SHM is related to frequency f by:

Answer: ω = 2πf.

  • A ω = 2πf
  • B ω = f/2π
  • C ω = πf
  • D ω = f

Correct answer: A. ω = 2πf

Explanation: ω = 2πf (angular frequency in rad/s = 2π times frequency in Hz).

Displacement, Velocity, Acceleration in SHMx(t)v(t)a(t)v leads x by 90°; a is exactly out of phase with x (a = −ω²x)

In SHM, displacement and velocity are 90° out of phase (v is maximum when x=0, and zero when x is extreme), while acceleration is always exactly opposite in sign to displacement, consistent with a = −ω²x.

Concept context

Simple harmonic motion, spring-mass, pendulum, energy in SHM, and resonance.
