单摆实验的研究

Research on the Period of a Simple Pendulum

应用PASCO数字实验教学系统对影响单摆周期测量的因素进行测量和估算,主要内容包含:摆角、相同体积不同质量的摆球、空气浮力、光电门的位置以及起摆的方向对周期测量的影响。

The influence of the vibration period of simple pendulum is studied by PASCO Digital lab system. The accuracy of the period of a simple pendulum is analysed through the different quality of the ball,the direction vibration of simple pendulum and the varying place of photogate.
