# 2018.10.25 Desired Jerk

From RooKwiki

The derivative of position with respect to time is velocity.

The derivative of velocity with respect to time is acceleration.

The derivative of acceleration with respect to time is... jerk.

No, really. It's a physics term.

This was relevant to me as I was delighting myself driving GHOST to work this morning. Because, while it is true that GHOST's acceleration is awfully nice - and what gets measured by all the numbers-obsessed - it's the broad prowess to adjust that acceleration that really is a driving delight. Because that's what engaged driving is really about for me: control.

I'm not too bothered by the double entendre, either.
