In Fashion photography - particularly high fashion - movement(action) is used regularly. It is used as a way to give the garment itself more life, creating texture and showing how its reflected in light; whether it's shiny, dull, etc.
In physics, action is an attribute of the dynamics of a physical system. It
is a functional which takes the trajectory (also called path or history) of the
system as its argument and returns a real number as the result.
