This model is designed for the study simple harmonic motion, given by the formula x = x_{m}cos(ωt + φ_{0}) Modify the amplitude x_{m}, the period T = 2π/ω of the oscillations, and the initial phase φ_{0} of the harmonic motion of a body. Observe changes in the motion of the point along the graphs of the x coordinate, of the velocity v and of the acceleration a. It is convenient to draw x, v/ω, a/ω^{2} on the ordinate axis, because they have the same units of measurement. Pay attention to the phase shifts between the coordinate, velocity and acceleration of the body.
