Self‐consistent and universal description of friction and diffusion for Brownian particles in such various systems as dusty plasma and active particles (e.g., cells in biological systems) is presented. Generalized friction function is determined to describe the friction force itself as well as a drag force in the case of non‐zero driven ion velocity in plasmas. (© 2003 WILEY‐VCH Verlag GmbH & Co.
