Differential of acceleration

[Ali Asadullah]

We know that a=dv/dt but what is differential of acceleration. Mathematically is it second derivative or simply d(dv)/dt.


(I am not asking about derivative of acceleration which is jerk) :confused:

[mathman]

da/dt = d2a/dt2, which is jerk. da as such would only be used as part of the definition of an integral where a is the variable of integration.
