高中物理必修教材中,有三个学生实验要使用打点计时器,其中“验证机械能守恒定律”是会考操作考查实验之一。实验室里打点计时器的使用率较高,因而经常会发生故障而影响实验效果。
In the high school physics compulsory textbooks, there are three students who are required to use a tick timer. The “Verification of the conservation of mechanical energy” is one of the exam exam operation experiments. The use of dot counters in the laboratory is high, so failures often occur and affect the results of experiments.
