试析圆周运动中的加速度

On the acceleration in a circular motion

本文首先分析了学生对于加速度概念存在错误认识的原因,然后通过用自然坐标法对做圆周运动中物体的加速度进行深入分析,得出做圆周运动物体加速度的几个特点,据此提出避免学生错误认识的两个教学策略。

This paper first analyzes the causes of students for the acceleration of misunderstanding, and then in-depth analysis by using natural coordinate method to make objects in circular motion acceleration, can do some features of circular motion object acceleration, puts forward two teaching strategies to avoid the wrong understanding of the students.
