“位移”是人教版高中《物理》必修1第1章“运动的描述”第2节中的一个力学基本概念,也是构建其他概念的元概念.它是指用来描述物体位置变化的物理量,是学生学习高中物理遇到的第一个矢量.位移概念的理解直接影响着后续概念的学习,如速度、平均速度、瞬时速度的理解,因它 “Displacement ” is a basic concept of mechanics in Section 2 of PEP 1 in Chapter 1 of Physical Description of Physical Education PEP.It is also a meta-concept for constructing other concepts.It refers to the meta-concepts used to describe objects The physical quantity of position change is the first vector that students encounter when they learn physics in high school.The understanding of displacement concept directly affects the learning of follow-up concepts such as speed, average velocity and instantaneous velocity as it
