Using the differential equation of linear S.H.M., obtain an expression for acceleration, velocity, and displacement of simple harmonic motion. Mean position is the central position where particle’s displacement is zero or where particle is at equilibrium position. In simple harmonic motion (SHM), the angular velocity measures the angular speed of the oscillating or rotating body. When the displacement is maximum, however, the velocity is zero; when the displacement is zero, the velocity is maximum. The motion of a simple harmonic oscillator repeats itself after it has moved through one complete cycle of simple harmonic motion.
