在“用单摆测定重力加速度”实验中,需要测摆长和周期这两个物理量,实验器材与装置都比较简单,但学生在实际操作过程中仍会存在不少问题,教师应针对其具体情况及时正确引导与处理,以便实验结果准确有效.现将实验操作中易出现的错误及其正确处理方法列举如下,供同行们参考. In the experiment of measuring gravitational acceleration with pendulum, we need to measure the length and period of the two physical quantities, experimental equipment and devices are relatively simple, but the students in the actual operation there are still many problems that teachers should focus on The specific circumstances in a timely manner to guide and deal with correctly, so that the experimental results are accurate and effective now easy to experiment in the operation of errors and their correct treatment are listed below, for their colleagues for reference.
