笔者在教学过程中,发现学生从学弹力时,对物理的信心开始动摇,对物理的学习兴趣开始减退,而阻碍学生学习脚步的就是从弹力的方向的判定,我们知道,弹力是建立力学知识体系的重要的一个力,如果我们在弹力方向上判断出了问题,那么,对于后面的摩擦力肯定是有一定影响的,因此,笔者就弹力的方向做了一点探究,掌握了一点技巧,这对绝大数的题目还是适应的,拿出来和大家分享,不到之处,还请批评指正。
In the process of teaching, I found that students began to waver in their confidence in physics when they began to learn, and their interest in physics began to diminish. Judging from the direction of elasticity, students’ hurdles in learning the footsteps were we know that elasticity is the foundation of mechanical knowledge System of an important force, if we determine the direction of the elastic direction of the problem, then, for the friction behind certainly have a certain impact, therefore, the author made a little exploration on the direction of elasticity, mastered a little skill, which On the vast majority of the subject is still adaptable, come up and share with you, not yet, but also criticism and correction.
