摘要/Abstract

摘要： 摩擦力是物理力学教学的难点,由于摩擦力问题的复杂性,导致学生对摩擦力的理解和认识十分困难,影响了学生对物理学重要概念形成过程的认知和物理学核心素养的形成。本文从摩擦力概念的理解、产生的条件和方向的判定、摩擦力与物体运动的关系和产生的效果等方面做了范例性讨论,尝试从理论层面对物理教学中关于摩擦力的教学提供实践路径。

Abstract: Friction is a difficult area of mechanics teaching in secondary school physics. The complexity of the friction problem leads to difficulties in the students' understanding and knowledge of friction and undermines their cognition of the formation process of important concepts in physics and the formation of core physics literacy. By presenting a paradigmatic discussion on the understanding of the concept of friction, the conditions of its generation and the determination of its direction, the relationship between friction and the motion of an object and the effects it produces, this paper attempts to provide some practical path for teaching friction in secondary school physics from the theoretical level.
