通常对摆钟问题的解法较繁,学生不易理解。现介绍一种思路简单容易求解的方法。 [题目] 每一昼夜慢6分钟的摆钟,其摆长为99.1厘米,若要使摆钟走时准确,应如何调整它的摆长? 解题的关键在于弄清摆钟的指示时间t_0=(60×24—6)分与摆钟的运行时间t=60×24分的区别。
The solution to the pendulum clock problem is often complicated and difficult for students to understand. Now we introduce a simple and easy-to-solve method. [Title] The pendulum clock is 69.1 centimeters long and slow for each day and night. How to adjust the pendulum length if the pendulum clock is accurate? The key to solving the problem is to find out the time of the pendulum clock t_0 = ( 60 × 24-6 minutes and the pendulum clock running time t = 60 × 24 points difference.
