摘要
木板倒地与板顶端小球自由下落时间研究隋峰，卢永智（陕西师范大学物理学系，西安７１００６２；第一作者，女，３６岁，讲师）１微分方程设匀质条板长为ｌ，质量为ｍ，一端用铰链接连，距铰链Ｉｃｏｓａ处固接一小盒．条板顶端有一小球．起始时条板与过其一端的水平面的...
The author study the free falling time of ball from top of strip board and of the board itself to level with numerical analysis, the reason that the both time are different is given,and calculated the angle between the board and the level when the boil and the board falling to the level simutaneously,the result is asme as experiment.
