If the period of a spring vibration is 4S, the period of the acceleration change of the oscillator is___ The period of velocity change is___ .

If the period of a spring vibration is 4S, the period of the acceleration change of the oscillator is___ The period of velocity change is___ .

It's also 4S, because it's directional!
And can draw the image! All are congruent sine function image
It's just that the starting point is different!
