滑块质量对气垫导轨测量重力加速度的影响分析

Influence of Slider Mass on Measuring GraviTb Acceleration of Air Cushion Guide Rail

重力加速度的测量方法很多,其中基于气垫导轨是相对其他方法来说误差较小的一种,为了进一步减小测量误差,实验基于气垫导轨通过改变滑块质量进行重力加速度的测量,以探究滑块质量的变化是否会对重力加速度的测量值造成影响。通过对实验结果的分析可知,重力加速度测量值与滑块质量在一定范围内变化无关。

There are many measurement methods of gravity acceleration,among which the air cushion guide rail has a smaller error than other methods.In order to further red-uce the measurement error,the experiment is based on the air cushion guide rail to meas-ure the gravity acceleration by changing the slider mass,so as to explore whether the ch-ange of slider mass will affect the measured value of gravity acceleration,Through the a-nalysis of the experimental results,it can be seen that the measured value of gravity acc-eleration has nothing to do with the change of slider mass in a certain range.
