很多人都认为物理这门学科的知识学了没有太大的用处,因为在实际生活中,的确也很难想象会在什么场合要用到“连接体”等高中物理中这类典型问题。即使有些人将来从事科技工作,如果不是去作大学或者中学的物理教师,恐怕也很少需要在这样的层次上去应用牛顿第二定律。这就似乎涉及一个很直接的 Many people think that the knowledge of physics in this discipline is of little use because in actual life it is indeed hard to imagine the typical problems that will be encountered in high school physics such as the “connector” . Even if some people are going to work in science and technology in the future, it is seldom necessary to apply Newton’s Second Law at such a level if they are not going to be physical teachers in universities or high schools. This seems to involve a very direct
