Learn Stokes’ Law in simple words – its statement, formula, step-by-step derivation, key assumptions, and practical applications. Understand viscous force and fluid motion with easy examples for students. Stokes' law is a mathematical formula that describes the drag force preventing tiny, spherical particles from falling through a fluid medium. Contents Physics Topics such as mechanics, thermodynamics, and electromagnetism are fundamental to many other scientific fields. What is the Formula for Terminal Velocity? Terminal Velocity of a Body in a Viscous Medium and Stokes’ Law When a body falls through a viscous medium (liquid or gas), it drags a layer of the fluid adjacent to […] Using Stokes’ Law provided in the lab manual, determine the viscosity (m) of the fluid using the average velocity of the three spheres. A common unit of viscosity is the Poise, or 1 g/cm.s.
