在初中物理考试中,通常用差值法解压轴题,解这类题需要构造新的“元素”.利用物理量的差值来解初中物理习题,不仅可以有效的简化解题过程,还能够提高中学生的物理知识水平.一、初中物理中差值法解题的优势针对初中物理习题,由于物理量之间存在差值,可以直接运算.有一部分题目,学生并不明白怎样解题,学生应用差值法解题,可以巧妙地解决这类难题.初中物理中,差值法不需要直接将数据带入公式进行求解,是利用物理数据之间的差值,
In the junior high school physics examination, the difference method is usually used to solve the axis problem. To solve such problems, we need to construct a new “element.” Using the difference of physical quantities to solve junior middle school physics exercises can not only effectively simplify the problem solving process, Can improve the level of physical knowledge of junior high school students.A, junior middle school physics difference in the advantages of the problem-solving For the junior high school physics exercises, due to the differences between physical quantities, you can direct computing.A part of the problem, students do not understand how to solve problems, students The application of difference method to solve problems, can skillfully solve such problems.Under junior physics, the difference method does not require the data directly into the formula to solve, is to use the difference between the physical data,
