运用数学知识解决物理问题是高考的能力要求之一,而高中数学增加了导数等高等数学的基础知识,这些知识对于解部分高中物理试题有很大帮助.例如解决牵连物体的速度问题时一般采用速度分解法、微元法、能量法等,其实对于此类问题完全可以利用导数知识来求解,下面就举几个例子供读者参考.例1 如图1所示,一个人在岸上以速度
The use of mathematical knowledge to solve physical problems is one of the requirements of the college entrance examination, and high school mathematics has added basic knowledge of derivatives such as advanced mathematics. This knowledge is of great help in solving part of the high school physics test questions. For example, it is commonly used to solve the speed problem of implicated objects. Speed decomposition method, micro-element method, energy method, etc., in fact, can fully use derivative knowledge to solve such problems, the following gives a few examples for readers to refer to. Example 1 As shown in Figure 1, a person on the shore with speed
