Jolt

Thursday, 19 November 2009 20:14 Bruno Lebon

The jolt (or jerk in American English) $\vec{\dot{a}}$ is the limiting value of $\frac{\Delta \vec{a}}{\Delta t}$ as $\Delta t$ approaches zero (i.e. the rate of change of acceleration):

$\vec{\dot{a}}=\lim_{\Delta t\to 0}\frac{\Delta \vec{a}}{\Delta t}={\operatorname{d}a\over\operatorname{d}t}$

The SI unit for jolt is the metre per second cube (m s^–3).
