一个令人深思的问题这是1980年的事了.一名高中女生,在物理课上学了弹簧和单摆的知识后,知道它们的振动都是有规律的.她想:要是用弹簧做成一个摆,它的振动是否也有规律呢?她推测:弹簧摆的振动应该是有规律的,并推断:一、弹簧摆的振动周期,应是弹簧和单摆振动周期的最小公倍数;二、振动的轨迹应是一个规则的图形.这个结论对不对呢?她做了几十次实验,积累了几百个数据,终于得出预想的结果.她据此写成的小论文,在
A thought-provoking question This was 1980. A high school girl who learned the spring and pendulum physics lessons in physics learned that their vibrations were regular, and she thought: If made of spring A pendulum, whether its vibration is regular? She speculated: the spring pendulum vibration should be regular, and inferred: First, the spring pendulum vibration cycle should be the spring and the pendulum cycle of the least common multiple; Second, the vibration The trajectory should be a regular graph .What is wrong with this conclusion? She did dozens of experiments and accumulated hundreds of pieces of data to finally arrive at the expected result.
