基于 Matlab 的小球在粘滞液体中下落运动的研究

摘要

研究了不同直径的钢球在甘油中下落过程中的运动规律，实验表明：不同直径钢球的运动规律应用不同的粘滞系数公式表示。同时，利用Matlab软件对不同直径的钢球在液体中的运动速度、加速度、加速运动的距离等物理量进行了计算和拟合。%The law of different diameters steel balls movement in glycerol have been studied using experi -ment,results show that the motion law of the different diameter of steel balls should use different viscosity coefficient formulas .At the same time ,some physical quantities have been calculated and simulated such as acceleration ,acceleration distance in viscosity liquid of steel balls utilizing the Matlab software .
