Term: Stokes law
https://doi.org/10.1351/goldbook.S06028

Definition:
F = 6π.η.r.v, where F is the force exerted on a sphere of radius r which is moving through a fluid of viscosity η with a relative velocity v; this equation holds at low velocities which are free from turbulence (called the stokes region).
