  "id": "MLC-T-CHM-004676",
  "term": "Frictional coefficient",
  "field": "Chemistry",
  "definition": "A proportionality constant that relates the frictional force experienced by a particle or macromolecule moving through a fluid to its velocity. This coefficient depends on the size, shape, and surface properties of the particle, as well as the viscosity of the fluid. It is a key parameter in describing the diffusion and sedimentation of polymers in solution.",
