概念是符合客观事实、反映相似物的共同性质和同类现象的特征的抽象的概括。物理概念是物理知识的基本组成部分,是物理定律、公式的理论基础。帮助学生形成正确的物理概念,准确理解物理概念的含义,是物理教学中的首要任务。关于“弹力,的概念,新编高中物理课本(甲种本)第一册和(乙种本)上册第十二页均写为”发生弹性形变的物体,由于要恢复原状,会对跟它接触的物体产生力的作用,这种力叫做弹力,,我认为,这一说法似
Concepts are abstract generalizations that are consistent with objective facts, reflect the common nature of similarities, and the characteristics of similar phenomena. The concept of physics is the basic component of physics, and it is the theoretical foundation of physical laws and formulas. Helping students form the correct physical concepts and accurately understand the meaning of physical concepts is the primary task in physics teaching. Regarding the concept of “elasticity,” the first book of the new high school physics textbook (the first edition) and the second book (the first edition of the second edition) are both written as “The object that has undergone elastic deformation will be reverted to its original state.” The force that comes into contact with it creates a force. This force is called elasticity. I think this is like
