A harmonic oscillator can be approximated by an oscillating mass attached to a spring under the effect of a force of type F=kx. The motion produced of this type is given by an oscillator x=Asin(2fx+)+x0 where A is an amplitude of oscillation, f is a frequency of oscillation, is a phase and x0 is an equilibrium position of the oscillator. In an experiment with a harmonic oscillator, the position (x) of the mass was averaged as a function of time (t). The data obtained are shown in the table below.
