'''Lagrangian Coordinates'''

</dt><BR/>1. A system of [[Coordinates|coordinates]]
by which [[Fluid Parcels|fluid parcels]] are
identified for all time by assigning them coordinates which do
not vary with time. Examples of such coordinates are: (a) the
values of any properties of the fluid conserved in the motion;
or (b) more generally, the positions in space of the parcels
at some arbitrarily selected moment. Subsequent positions in
space of the parcels at some arbitrarily selected moment. Subsequent
positions in space of the parcels are then the dependent variables,
functions of time and of the Lagrangian coordinates. Also called
''material coordinates. ''Compare [[Eulerian Coordinates|Eulerian
coordinates]]. See [[Lagrangian Equations|Lagrangian
equations]].
</dd><BR/>2. Same as generalized coordinates. [[/a>|/a>
