Stokes's law

Stokes's law describes how a small, spherical object moving slowly through a viscous fluid (like honey or oil) experiences a resistive force called drag. It states that this drag force is directly proportional to the object's radius, the fluid's viscosity, and the velocity of the object. In essence, larger objects, thicker fluids, or faster movement result in greater resistance. This law helps in understanding particle settling, fluid flow around small objects, and designing various engineering and scientific processes involving fluid dynamics.
