摩擦力的第一节课的授课内容,个人认为要打破常规,讲清摩擦力的产生和摩擦力的方向。让学生课前、课时、课后通过实验体会物理知识的形成及应用,为下面的力学打下好的基础,不至于让摩擦力打倒一片学生。
Friction of the first class of lectures, personally think that we should break the routine, to clarify the friction generated and the direction of friction. Allow students to class before class, class, after class by experiment experience the formation and application of physical knowledge for the following mechanics laid a good foundation, will not let the friction down a student.
