Re: Definitions



The term "static equilibrium" is integral; "static" is not a modifier.
"Equilibrium" is a less precise near synonym which may be used when no
confusion can arise.

Perhaps the term "dynamical equilibrium" is appropriate to equilibria
established within a noninertial frame of reference. I'm thinking of
the status of particles at the L4 and L5 points in the restricted
three body problem which was elaborated by Joseph Lagrange. There are
many other similar examples in celestial mechanics.
