Dynamics etymologigally means "competition of forces" i.e it does not convey anything about kinematical or motional connotations.Despite of this, in physics it is used as term for the marriage of kinetics and forcive physics.
Despite these linguistic confussions or mishaps, dynamics if a functional domain in its relation to kinetics, nevertheless. It is, in the theoretical realm, the precursor to kinetics i.e it mothers equations of motion.
In field theory, the conceptual counterpart to dynamics is "field equations". Whst culd a different name that convey the same motherhood relation to classical kinetics be, to spare dynamics?
