加速度是最基本、最重要的物理量之一.处理很多物理问题时,加速度担当着重要角色.为此,本文通过对加速度的探讨,帮助学生再度认知和重新建构有关加速度概念.1.从运动学的角度认识加速度为了描述速度变化快慢,引入加速度的概念.加速度是表示速度改变快慢的物理量,它等于速度的改变跟发生这一改变所用的时间的比值. Acceleration is one of the most basic and important physical quantities.Acceleration plays an important role in dealing with many physical problems.To this end, this paper helps students to recognize and reconstruct the concept of acceleration again through the discussion of acceleration.From the perspective of motion Learning to Understand Acceleration In order to describe how quickly a velocity changes, the notion of acceleration, a physical quantity that indicates how fast a velocity changes, is equal to the ratio of the change in velocity to the time it takes to make that change.
