Brownian movement. n. 1. (General Physics) random movement of microscopic particles suspended in a fluid, caused by bombardment of the particles by molecules of the fluid. First observed in 1827, it provided strong evidence in support of the kinetic theory of molecules.
Brownian motion is the random motion of particles in a solution  resulting from their collisions. Diffusion happens as more and more  collisions happen between the particles â¦ , they become more  interspersed with each other.Ananda Ayyappan JV.he process is called kinetic energy witch is the Random movement of atoms or molecules.
