PHYS 233 - Physics for Life Sciences Lab report 4 (Competition Between Brownian Motion and Directed Forces) Purdue University

PHYS 233 - Physics for Life Sciences (Lab report Analysis of Brownian Motion) Purdue University Abstract In this Lab for PHYS 233, our goal was to determine the diffusion constant for beads of different sizes (1, 2, and 5 microns), different densities (silica versus polystyrene), and different fluid viscosities (water, low glycerol concentration, high glycerol concentration). These beads move in brownian motion which is the random motion of beads. The class results shows that the diffusion con...
