| 摘 要： | 重力加速度的测量作为普通物理经典实验,在普通物理实验中常用单摆法或自由落体运动法来测量。本文提出一种新的测量重力加速度的方法——用弦振动测当地重力加速度,并对测量原理公式进行较为详细的推导,用测量结果与理论值及单摆法测量值进行比较,得出用弦振动测当地重力加速度也比较准确。

| Abstract: | The measurement of gravity acceleration is one of the classic physics experiment.Generally,the pendulum method or the free falling motion method is used.This paper presents a new method for measuring gravity acceleration using the string vibration,and the measuring formula is derived in detail.Also the physical principle is clear and the operation is rather simple.Compared with the measuring result of pendulum method,the string vibration is more accurate. |
