Video Analysis of Spheres Falling Through Two Liquids

Introduction Providing accurate fluid-dynamics experiments for undergraduate laboratories is challenging in several ways, including reproducibility, simplicity, and accessibility for introductory students. Data from many introductory experiments, for example, are not sufficiently precise to decide whether a linear or quadratic relationship better models the dependence of drag force on velocity. An optimal laboratory experiment is inexpensive…
