分析问题时,思维由方程式从左到右是顺藤摸瓜,受力决定运动,水到渠成,而从右到左是追根求源,运动反映受力,是逆向思维。要想正确处理物理问题,必须搞清物理情景,而物理情景往往是由物体运动情况反映出来的,因此解答圆周运动问题时逆向思维较适宜。 Analysis of the problem, the thinking from left to right is the formula to follow the example, the force determines the movement, come into its own, and from right to left is the root, the movement reflects the force, is reverse thinking. To correctly deal with physical problems, we must understand the physical situation, and the physical situation is often reflected by the movement of objects, so the answer to circular motion problems more appropriate thinking.
