…and m is its mass. The force acting on the particle is written as a sum of a viscous force proportional to the particle's velocity (Stokes' law), and a noise term η ( t ) representing the effect of the collisions with the molecules of the fluid. The force η ( t ) has a Gaussian probability distribution with…
