物理力学中的摩擦力知识是初中物理教学的重点,也是难点。学习摩擦力知识需要一定的思维能力,物理教师在教学时也要注重引导学生从实际出发,结合情境。就此对摩擦力教学做一些探究。 Knowledge of friction in physical mechanics is the focus of the physics teaching in junior high school, but also difficult. Learning friction knowledge requires a certain ability of thinking, physical teachers in teaching should also focus on guiding students from the reality, combined with the situation. In this regard to do some research friction teaching.
