Definition of Brownian motion. : a random movement of microscopic particles suspended in liquids or gases resulting from the impact of molecules of the surrounding medium âcalled also Brownian movement.
What causes Brownian motion? A: Brownian motion is caused by the impact of fluid molecules or atoms in rapid and random motion from heat on small particles suspended in the fluid. Brownian motion, which tends to disperse particles as widely as possible, is the major force in diffusion. Brownian motion occurs in small suspended particles, regardless of any overall movement or current in the suspending fluid.
