These are the points where position, velocity pass through zero. In the analysis of essentially sinusoidal signals, these zero crossings are easily detectable and can be used to determine the period and frequency of a cyclical waveform with greater precision than measurements of peak values and their time of ocurrence.

a) = this is when the object is back at its starting position
b) = This is when the object is at its starting velocity.
they both depend on the scale so I dont want to call it zero.
