It appears that the proper term for this is "the jerk".

No, really, just in case the website I looked on was a spoof, I checked the ISO 2041 document:

https://www.iso.org/obp/ui/#iso:std:iso:2041:ed-3:v1:en

and jerk is the rate of change of acceleration.

There is some suggestion that over here in the UK, the term "jolt" is an acceptable alternative and too my ears that would sound better...

(Personally, I was expecting the term "impulse" but it seems that the engineers objected.)
