高一物理现行课本简谐振动的周期一节,对简谐振动周期公式,只给出了结果没有推导过程,学生学过之后印象不深,如果教师在讲授时用实验验证一下,可以收到事半功倍的效果. 多数学校都有如图1所示的演示弹簧振子.如果用弹簧振子验证公式,则公式中的m表示振子锤的质量,k表示弹簧的倔强系数.
The period of harmonic vibration in the textbook of the current physical textbook of the Physics Department, for the harmonic vibration cycle formula, only gives the result without the derivation process. The students do not have a deep impression after learning it. If the teacher uses the experimental verification to teach it, they can receive it. Efforts to do more with less. Most schools have a demonstration spring oscillator as shown in Fig. 1. If a spring oscillator is used to verify the formula, then m in the formula represents the mass of the vibrator hammer, and k represents the spring’s stubbornness coefficient.
