在高中物理实验中利用打点计时器来测定匀变速直线运动的加速度,为了减小实验的偶然误差,把多次测量的加速度的平均值作为实验结果,具体做法一般为:
In the high school physics experiment, use the dotting timer to measure the acceleration of the uniform linear motion. To reduce the accidental error of the experiment, the average value of the multiple measurements of acceleration is taken as the experimental result. The specific method is generally as follows:
