摘要
描述了网球垂直下落过程中与振动台面相撞击的运动状态,首次求取了该运动的数学解析方程和差分方程,设计了相应的程序,并通过图像直观地反应了网球的运动轨迹随参数的变化情况,为了满足学生课堂实验的要求,进一步设计了网球反弹轨迹仿真系统,此项研究对于促进和提高网球运动的研究水平,对于帮助学生对一些物理概念的理解都具有积极的作用.
In this paper, the movement of the vertical motion of tennis ball collided with the oscillatory table- board is explained, the mathematic equation and difference equation is procured and the corresponding programs are designed, the corresponding physical background visually with the picture is stated. In order to satisfy the need of students in classroom, the simulation system is designed. It＇ s very active for studying and researching the motion of tennis ball.
