Translational frictional coefficient

{
  "id": "MLC-T-CHM-012249",
  "term": "Translational frictional coefficient",
  "field": "Chemistry",
  "definition": "A measure of the resistance encountered by a molecule or particle as it moves through a fluid, opposing its translational motion. This coefficient relates the frictional force to the velocity of the particle. It is directly proportional to the size and shape of the particle and the viscosity of the medium, and is inversely related to the translational diffusion coefficient.",
