高中物理三大常见的力中的摩擦力是学生学习的一个重、难点知识,对于摩擦力的学习,学生往往有一个误区:摩擦力是阻力,与运动方向相反。因此,在解题过程中不假思索,得出错误结论。 Friction among the three most common high school physics is a heavy and difficult knowledge for students to learn. Students often have a misunderstanding about friction learning: friction is resistance and opposite to movement. Therefore, in the process of solving problems without thinking, come to the wrong conclusion.
