Stokes’ Law Formula
The following equation is used to calculate the terminal velocity of an object.
v = g * d^2 * (P – p) / (18 * u)
- Where v is the terminal velocity
- g is the acceleration due to gravity
- d is the diameter of the particle
- P is the density of the particle
- p is the density of the fluid
- u is the viscosity of the fluid
Stokes’ Law Definition
Stokes’ law is defined as the terminal velocity of a falling object through a specific fluid or medium.
