Abstract	MEMs gyros, such as those in smartphones allow the angular velocity of pendulums to be precisely measured at large angles, and phase plots of the angular acceleration versus the angular displacement confirm that [double dot][phi] = -[omega][superscript 2][subscript o] sin[phi] even for the non-sinusoidal motion at amplitude [phi][subscript o] [approx] [pi]. For amplitudes [phi][subscript o] > [pi]/2 the angular acceleration has extrema of \|[double dot][phi]\| = [omega] [superscript 2] [subscript o] at angular displacement [phi][subscript o] = ±[pi]/2, i.e. the four times per oscillation that the pendulum is horizontal. (As Provided).
