“整体思维法”就是把相互联系的几个物体当作一个整体(或把几个物理过程当作一个过程)进行的研究方法,这种方法用于解题中,往往可以少走弯路,或跳过常规步骤,使解法简捷而明快。运用此法要纵览全局,通盘考虑,做到目标明确,有的放矢。要防止那种“只见树木,不见森林”的片面做法。现就此法在初中物理中的运用举例说明如下: 例1 甲、乙两头牛从相距L千米的A、B两地,以同样的速度V1沿直道匀速相向而行,同时,甲牛头上的一只蜜蜂以V2的速度(V2)V1匀速向乙牛飞去,触到乙牛头部即刻返回,再去触碰甲牛,这只蜜蜂一直在两牛间匀速往返飞行(触碰时间不计),直至两牛相遇,问这只蜜蜂共飞行了多少千米? The “whole thinking method” is a research method that considers several interconnected objects as a whole (or considers several physical processes as one process). This method is used to solve problems, and it is often possible to avoid detours, or Skip conventional steps to make the solution simple and clear. Use this method to take a look at the overall situation, consider it comprehensively, and achieve a clear goal and target. We must prevent the one-sided approach of “seeing only trees and not seeing forests.” The example of the use of this method in junior high school physics is illustrated as follows: Example 1 A and B two cows move from A and B two kilometers apart from each other at a uniform speed V1 along the straight road, and at the same time, on the head of a cow. A bee flies at a uniform speed of V2 (V2) V1 to B, and touches B’s head to return immediately, and then touches A. The bee has been flying at a constant speed between the two cows (touch time is not counted) Until the two cows met and asked how many kilometers the bee had flown.
