Abstract

The Falling Ball Method is a method of measuring the viscosity of a fluid by observing the speed at which a small ball falls through the fluid. This method is based on Stokes' Law, which states that the drag force on a spherical object moving in a fluid depends on the viscosity of the fluid, the size of the sphere, and its speed of motion. This study aims to determine the effect of dilution level and syrup type on viscosity using the Falling Ball Method. This method is based on Stokes' law, where viscosity is determined based on the speed of the falling ball in the solution. The syrup samples used consisted of several types with variations in concentration of certain dilutions. A metal ball was dropped into a tube containing syrup, and the time taken to reach a certain distance was measured using a stopwatch. The results showed that the higher the level of dilution, the lower the viscosity of the solution. In addition, the difference in syrup type also had a significant effect on the viscosity value, where syrups with higher sugar content tended to have greater viscosity. This study shows that the falling object method is effective for measuring viscosity and can be used in physicochemical analysis of various types of liquids.
