我在高一物理教学中,遇到较多的学生提出“水滴沿伞边切线飞出”的质疑问题。为了用实验验证“当水滴从伞边飞出时,可以看到水滴是沿着伞边各点所划圆周的切线方向方飞出的”结论,用于解答学生对图1所示现象产生的疑惑,本人设计了如图2所示的实验装置,实验效果显著,有很强的说服力,具体做法如下: In high school physics teaching, I encountered a lot of students questioning the question of “flying along the tangent line of umbrella edge”. In order to use the experimental verification “When the water droplets fly out from the edge of the umbrella, you can see the water droplets flew along the tangent direction of the circumference circled by the points on the edge of the umbrella” to answer students’ questions about the phenomenon shown in Figure 1. Confused, I designed the experimental device shown in Figure 2, the experimental results are significant, there is a strong convincing, the specific approach is as follows:
