在中学物理中,弹力是出现最多的一种,同学们在分析有关弹力问题时,经常碰到各种各样的困惑.笔者从实际问题出发,就弹力的存在和方向的判断谈谈自己的浅见.首先要弄清楚的是弹力产生的条件:弹力是直接接触的物体间因发生弹性形变而产生
In the middle school physics, elasticity is the most common type. When classmates analyze problems related to elasticity, they often encounter various kinds of confusion. The author starts from practical problems and talks about the existence and direction of the elasticity. Shallow opinion. The first thing to be clear is the condition of the elastic force: the elastic force is generated by the elastic deformation of the objects that are in direct contact with each other.
