要解决运动物体间速度关联问题,关键是要找到速度间的关系,这往往是有些高考命题的切入点,而寻找这种关系也是考生普遍感觉的难点,要突破这个难点,我们要从以下几点来理解、掌握。一、分运动与合运动的关系1.一物体同时参与几个分运动时,各分运动独立进行,各自产生效果(~v分、~s分)互不干扰, To solve the speed-related problem between moving objects, the key is to find the relationship between speeds, which is often the entry point of some college entrance examination propositions, and finding this relationship is also a common difficulty for candidates. To overcome this difficulty, we need to Learn to understand and master. First, the relationship between sub-sports and joint sports 1.
