In the experiment on Page 2, you investigate the motion of several ball bearings as they fall in glycerin. The object is to examine the motion and to find the viscosity of the fluid. You are provided with a variety of steel ball bearings ranging in radius from 0.79 mm to 2.37 mm. The bearings are released into the center of a cylinder of glycerin using plastic tweezers. The value for the coefficient of viscosity of glycerin is approximately 1 N s m-2 (at 20oC).
