Definition:
A characterization of the density of particles located at a given point in
phase space (a combination
of either velocity or position coordinates) at a given time. The velocity-space
distribution function gives the number of particles with a particular velocity;
the position-space distribution function is synonymous with the particle
density in position-space. Different combinations of position and spatial
coordinates are useful in different problems.
