-
摘要: 该文建立了存在摩擦力情况下的质点沿固定半球面滑动的动力学微分方程并获得了解析解;确定了质点自球面顶端开始滑动所需要的初动能值的范围并找到了质点滑离球面时飞离角大小与摩擦系数的解析关系.Abstract: In this paper,we have discussed motion of particle on a fixed hemispherical smoothless surface and obtained following results; (1) Construct dynamical equation and gave its solution. (2) Establish range of particle initial kinetic energy . (3) Find out relation between escape angles and coefficient of kinetic friction.
