Abstract

The dataset contains the results of measurements of the braking distance of balls in layers of viscous liquids, depending on the acceleration distance on an inclined plane. Four viscous liquids were tested (glycerin, liquid soap, multiflower honey, and pine honey), resulting in a dataset containing 4 files. Six balls were used in the study: five steel bearing balls (with diameters of 10, 12.75, 13, 16, and 20 mm) and one cemented ‘wolfram’ carbide ball (with a diameter of 10 mm). A power-law viscosity index n, which appears in the generalized Stokes equation and the Ostwald–Weale equation, was fitted to each liquid. The case n=1 corresponds to the usual Stokes equation, as well as to Aristotle's ancient proportion of motion from Book VII of his Physics.
