So if Momentum is $m \cdot v$, Force is $m \cdot a$, and Jerk is $\frac{\Delta a}{\Delta t}$ what is $m \cdot j$? I've read that the name for this is yank, but I'm curious as to what it is conceptually. Can anyone explain this for me?

It's the rate of change of force with respect to time.

1$\begingroup$ @Ariana why would we need to assume mass as constant, F = ma therefore dF = d(ma) = a×dm + m×da, i think, mass needs not to be constant $\endgroup$ – PranshuKhandal Mar 6 at 2:43

2$\begingroup$ $F=\frac{dp}{dt}=ma+v\frac{dm}{dt}$, $\frac{dF}{dt}=mj+2a\frac{dm}{dt}+v\frac{d^2m}{dt^2}$ $\endgroup$ – Ariana Mar 6 at 2:45
