论文摘要
通过经验观察参与物理和物质特性是本科物理学和工程教育的基本组成部分。几项工作提出了实验,以确定材料的热物理常数,例如找到线性扩展的系数。如Dajbych和Polak等。已经表明,可以通过测量吉他上拔出的高碳钢电线的频率来完成实验验证物理常数的方法。在以前的工作的基础上,我们扩展了通过针对入门物理教育的可访问程序来验证线性热扩展系数的方法。
Engaging with physical and material properties through empirical observation is a fundamental part of undergraduate physics and engineering education. Several works have proposed experiments to determine thermal physical constants of materials such as finding the coefficient of linear expansion. As Dajbych and Polak et al. have shown, methods for experimentally verifying physical constants can be done by measuring the frequency of a plucked high-carbon steel wire on a guitar. Building upon our previous work, we have extended our method to verify the coefficient of linear thermal expansion through an accessible procedure directed at introductory physics education.
