WebBrownian motion is the random motion of particles suspended in a medium. It is also known as pedesis. The particles subjected to Brownian motion tend to follow a zig-zag path of movement, which causes a partial or complete transfer of energy between them. The particle size is inversely proportional to the speed of motion. WebParticle motion The particles in a gas are moving very quickly in random directions. The speeds of the particles vary but, on average, they move quicker than they do in liquids and …

At very short time scales, however, the motion of a particle is dominated by its inertia and its displacement will be linearly dependent on time: Δ x = v Δ t. So the instantaneous velocity of the Brownian motion can be measured as v = Δ x /Δ t, when Δ t << τ, where τ is the momentum relaxation time. See more Brownian motion, or pedesis (from Ancient Greek: πήδησις /pɛ̌ːdɛːsis/ "leaping"), is the random motion of particles suspended in a medium (a liquid or a gas).
