初中的物理知识的习题有着复杂、烦琐、难度大并且抽象等特点,学生如果欠缺良好的解答方法,那么学生在解答问题时将会遇到很多困难,所以学生一定要注重解题方法的归纳总结,将复杂的问题转变的简单,从而更好地理解和掌握习题内容,这对提高学生物理知识学习能力有着非常大的帮助。一、归纳总结在解答《杠杆》习题中的运用1.习题一:通过下图的杠杆A点来画出动力(图一) Junior high school physics problems with complex, cumbersome, difficult and abstract characteristics such as the lack of a good student answer methods, then students will encounter many difficulties in answering questions, so students must pay attention to the method of induction summary , The complexity of the problem to change a simple, so as to better understand and grasp the exercise content, which enhance students ability to learn physical knowledge is very helpful. First, summed up in the solution to the “leverage” exercise 1. Exercise one: through the following lever A point to draw power (Figure 1)
