| Abstract: | The elastic collision mechanism of Brownian motion is studied,and the equipartition of kinetic energy of Brownian particle has been proved.The author shows how the collision between a Brownian particle and its surrounding molecules lead to the Lagevin equation,and gives us the subtle explanation of damping and stochastic forces. |
