Stokes' Law states that the drag force experienced by a spherical object moving through a viscous fluid is directly proportional to the velocity of the object, the radius of the object, and the viscosity of the fluid. Mathematically, it can be expressed as:
Fd = 6πηrv
Where Fd is the drag force, η is the dynamic viscosity of the fluid, r is the radius of the spherical object, and v is the velocity of the object.
