dynamical

The first of these groups of properties may be called dynamical; the others, chemical.

We are indebted to Professor Purser of Belfast for having indicated the true dynamical principle on which the problem depends.

Dynamical instability corresponds with the maximum of energy, and dynamical stability to the minimum of energy.

It is the force of inertia--the resistance which all matter opposes to a dynamical force exerted to put it in motion.

I wish to make it entirely clear, that in the dynamical sense of the term "force," there is no such thing as centrifugal force.
