# SIMPLE HARMONIC MOTION CALCULATOR

Simple Harmonic Motion Calculator to find period, frequency, angular frequency, amplitude, displacement, velocity and acceleration of simple harmonic spring oscillator in physics.

The mass of the spring is ignored in calculations. The spring is mounted horizontally and the mass m slides without friction on the horizontal surface. It is also assumed that Hooke's Law holds. ### Simple Harmonic Motion Calculator:

Note 1: Use dot "." as decimal separator.

Note 2: Cosine function (X = Acos(wt+φ)) assumes that the oscillating object starts from rest (v = 0) at its maximum displacement (x = A) at t=0 with phase angle 0. If at t = 0 the object is at the equilibrium position and the oscillations are begun by giving the object a push to the positive x direction, it would be a Sine function (X = Asin(wt+φ)) with phase angle 0. See simple harmonic motion example for more information about selection.
