position

Position is perhaps the most easily-measured observable.

It is one of the basic coordinates in both Lagrangean mechanics? (based on state space?, given by position and velocity?) and in Hamiltonian mechanics (based on phase space, given by position and momentum).

See also Position, Velocity, and Acceleration.
