The faster times should correspond to the least viscous liquids? 1. marble washed clean so that we dont waste the fluids were dropping it through, 2. /Filter /FlateDecode WebConclusion For this experiment, its main objective is to determine the viscosity of a certain fluid. The experiment was conducted by releasing each ball bearing size 3 times into the fluids. c^(Zf+?}qo Webweb air track physics lab report conclusion bing experiment 5 air track physicslessons com verifying the law of conservation of momentum jeremy vosen layer viscosity thickness surface area if a glider moves on a level track in the absence of any air track physics lab report conclusion bing Fweight=Fdrag+Fbuoyancy (1), We calculate the drag force acting on the ball by using the Stokes law equation, whereis the viscosity,Ris the radius of the ball bearing andvis the velocity of the ball. Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. Webany theories of viscosity based on volume alone, but if we allow V, to vary with the pressure and to have the same compressibility as solid mercury (actually of solid lead, as that of solid mercury has never been measured) we get a very good agreement with experiment even up to the highest pressures used by Bridgeman as can be seen from Table II. fv{gb0~!
