Simulation of Brownian motion affected by Gaussian force in gravitational field
Abstract
The velocity correlation and its spectral density of the Brownian motion were calculated by using microcomputer to display the characteristic properties of unsteady behavior of Brownian particles affected by an external force yielded in a constant gravity. It is shown that the Brownian motion is effected by both the ratio of the Brownian particle mass to the mass of a molecule agitating thermally as surrounding media and the value of the standard deviation of Gaussian distribution as the external force disturbing the Brownian motion.
