Since acceleration is the time derivative of velocity, the material acceleration can be derived from the definition of material derivative as follows:
Using only direction of vector
UNIT 2: DERIVATIVES
For an alternative derivation, we can make use of the usual vector operations to express the total second derivative of the absolute position vector r.
