Newton's law gives
For a fluid the acceleration is calculated following a fluid element.
Thus, we use the total time derivative. The applied force is due to
pressure forces,
, and any other external forces such as
gravity,
, and magnetic forces,
. Thus, each fluid element with mass
satisfies the Equation of Motion

. In this
course we shall not consider viscous forces and so we shall only deal
with an inviscid fluid.
