【Abstract】 By solving the falling sphere’s dynamic equilibrium equation in the water and on the bed, the corresponding equation of falling distance and the equation of steady falling distance are obtained respectively, based on the condition of two-dimensional flow. The obtained formulas have been proved to be in good agreement with the experimental data.更多还原
