This equation computes the amplitude of a simple harmonic oscillator, the maximum displacement experienced by the body in its oscillating motion.

When the restoring force is directly proportional to the displacement from equilibrium, the oscillation is called Simple Harmonic Motion (SHM).

Inputs

  • x0x0 - The initial displacement of the oscillating body at time t = 0
  • v0xv0x -  the initial velocity of the oscillating body at time t = 0
  • ωω - the angular velocity of the oscillation
