Third Derivative of Distance-Time Function - What is it Called?

[bomba923]

Hey um, what's the third derivative of the distance-time function?

d'(t)=velocity
d''(t)=v'(t)=acceleration
d'''(t)=v''(t)=a'(t)=??

I remember there was a special name for this function--but i can't remember what was; what is it called?

Jerk (or alternatively jolt).

The third derivative of the distance-time function is known as the jerk, or the rate of change of acceleration. It measures how quickly the acceleration is changing over time.
