物理问题各式各样,有些问题描述的物理现象、物理事件虽然不同,但结果和模式却惊人的相同.研究这类习题,对培养学生的创造性思维是大有裨益的.本文仅就这类习题的模式予以探讨.一、物理量为c=a+b模式的问题1.两端称重如图1所示,一棒形物体平放在地面上,图1用弹簧秤吊起一端称得 There are various kinds of physical problems. Some of the physical phenomena and physical events described by some problems are different, but the results and patterns are strikingly the same. Studying these types of exercises is very helpful for cultivating students’ creative thinking. The mode of exercise is discussed. First, the problem of physical quantity is c=a+b. 1. Weigh both ends As shown in Figure 1, a rod-shaped object is placed flat on the ground. Figure 1 uses a spring balance to lift one end.
