Stokes' Law describes the motion of spherical particles through a viscous fluid, specifically detailing how the velocity of a particle is proportional to the square of its radius and the difference in density between the particle and the fluid. This principle is crucial for understanding the stability and behavior of colloids, especially in contexts like emulsions, filtration, and water purification processes, where particle movement and separation are essential.
