气轨实验中根据公式:a=(v_B~2-v_A~2)/(2S) (1)a=(v_B-v_A)/t (2) 计算加速度a时,将有理论系统误差,此茶统误差与挡光片宽度d有关,但不一定从减小宽度去消除。一、掘根公式(1)测量时设滑块在起始位置时,挡光片的第1前沿距光电门A为S_0(图1),挡光片的第2前沿距第丑前沿为d,即挡光片宽度,光电门A、B间距离为S。当滑块从静止开始以加
In the air-rail experiment, when the acceleration a is calculated according to the formula: a = v_B 2 v_A 2 / 2S 2 a = v_B-v_A / t 2, there will be a theoretical systematic error. This tea The system error is related to the width d of the light barrier, but not necessarily eliminated from the reduced width. First, digging root formula (1) measuring the slider at the starting position, the first front edge of the light barrier from the photoelectric door A is S_0 (Figure 1), the second front edge of the light barrier ugly front edge for the d , That is, the width of the light barrier, photoelectric gate A, B distance between the S. When the slider starts from rest to add
