物理综合问题之所以复杂是因为它涉及物体的复杂运动.所谓复杂运动主要指运动在两个方面可能是复杂的.第一类是指物体的运动形式相对于简单运动(如匀速直线运动、匀加速直线运动、圆周运动等)是复杂的;第二类是指研究对象不止一个.其中,第一类又可具体分为两种情况:一是单个物体的运动过程长,全过程内运动形式变化多,可以分割成一段段的 The reason why the physics synthesis problem is complex is because it involves the complex movement of objects. The so-called complex movement mainly means that the movement may be complicated in two aspects. The first type refers to the movement form of the object relative to the simple movement (eg uniform linear motion, uniform Accelerating linear motion, circular motion, etc.) are complex; the second type refers to more than one study object. Among them, the first type can be divided into two specific cases: First, the long motion process of a single object, the form of motion within the entire process Many changes can be divided into sections
