f(x) - position df(x)/dx - velocity d2 f(x)/dx2 - acceleration d3 f(x)/dx3 - jerk

For velocity and acceleration you want to take derivatives with respect to time, not distance.

That's it! The slope vs acceleration thing was bugging me but I couldn't put my finger on why. Thanks.

And the fourth derivative is snap.

Position, velocity & acceleration. You didn't ask, but, third derivative is 'jerk' (a change in acceleration). Fun trivia!

What's the derivitive of a constant? Please use newtonian representation when discussing mechanics. Flys don't dot screens often these days.
