通过分析小球在水平面上往返弹跳的阻尼运动,推导出总路程和总时间跟高度衰减率与初始高度的数量关系,并用来解答有关相对运动的竞赛题.
By analyzing the damping motion of the ball in the bouncing back and forth on the horizontal plane, the relationship between the total distance and the total decay rate and the initial height is deduced and used to solve the competition question about the relative motion.
