2.3 Acceleration in the S.H.M.

As the S.H.M. is a rectilinear movement, its normal acceleration is zero. Therefore, the total acceleration coincides with the tangential acceleration and thus can be obtained from the derivative of the speed.

In the simplest case, the phase difference is nil (φ = 0) and the equation takes the form:
