在分析解决有关力学问题时,最常见的方法就是从物体的受力分析入手,明确物体的受力情况,根据运动和力的关系解决实际问题．现在根据课程标准要求编写的初中物理新教材,其明显的特点是将能量的观点融于其中,为我们解决有关力学问题提供了一个新的视角,下面就这方面的问题做一些探讨．
When analyzing and solving related mechanical problems, the most common method is to start from the force analysis of the object, clarify the force condition of the object, and solve the actual problem according to the relationship between motion and force. The new textbook for junior high school physics textbooks, which are now written according to the requirements of the curriculum standards, is clearly characterized by the integration of energy perspectives. It provides a new perspective for us to solve the problems of mechanics. We will discuss some issues in this area.
