重力加速度是中学物理教学的重要概念,在中学阶段比较准确地测量重力加速度大小的实验是单摆实验,用到了转换的方法.[1]但由于计时等原因,利用单摆实验测量重力加速度亦存在误差.[2]为此,笔者根据不同的实验原理,利用PASCO传感器来测量重力加速度,数据准确,而且可以在实验数据图表中观测实验过程,取得了非常准确的效果.
Gravity acceleration is an important concept in physics teaching in middle schools. Experiments that accurately measure the magnitude of gravity acceleration in middle school are single pendulum experiments and use the method of conversion. [1] However, due to timing and other reasons, the use of pendulum experiments to measure the acceleration of gravity There is an error. [2] To this end, according to different experimental principles, the author uses PASCO sensors to measure the acceleration of gravity, the data is accurate, and the experimental process can be observed in the experimental data chart, and very accurate results are obtained.
