所谓相对运动原理,是指任何运动都是相对于其参照物的静止而言的,而静止则是为了考察某种变化而选定的标准,参照物的选择决定着考察运动的角度和效果.如果我们将运动体作为其参照物变化的标准,那么运动与静止也可进行转换.这种原理不仅对我们解答有关物体运动的题目具有重要意义,而且有助于我们处理数学中变量与常量,动点与定点的关系,是一种重要的数学解题思想和策略,现结合初中数学实例,将
The so-called relative movement principle means that any movement is relative to the rest of its reference object, and static is a criterion selected to examine a certain change. The choice of a reference object determines the angle and effect of examining the movement. If we use the moving body as the standard of change of its reference, then motion and stillness can also be transformed. This principle is not only important for us to answer questions about the movement of objects, but also helps us to deal with variables and constants in mathematics. The relationship between moving and fixed points is an important mathematical problem-solving idea and strategy.
