摘要
学生在学习摩擦力时会产生认识误解,但只要围绕演示实验,讲清摩擦力产生的四个条件,结合实例培养学生分析能力,学生会正确认识摩擦力的。
It is possible that students misunderstand some substance on friction, when they study the topic of friction. If only a teacher elucidates the four generating conditions of friction in the shape of the demonstrative experiment, and fosters students' analysis ability by examples, the students certainly understand the substance on friction.
