测定重力加速度的两种方法

Two Methods for Measuring Gravitational Acceleration

采用单摆和自由落体试验仪都可以测定重力加速度。在单摆试验部分,系统地阐述了周期公式的由来与成立条件;在自由落体试验部分,利用2个光电门计时方式测定重力加速度的试验结果比较理想。两种不同试验方式所得结论得到了相互验证。

Simple pendulum and free fall experimental instrument are used for measuring the acceleration of gravity. In the simple pendulum experiment, the origin and establishing conditions of cycle formula are stated systematically. In the free fall experiment, Timing method by two optical switch is used and the result is satisfactory. The results of the two different experiments validate each other very well.
