Abstract

Abstract The development of a cost-effective experiment set is essential for teaching and learning physics in educational institutes. We aim to develop a computer-based simple pendulum experiment set consisting of a simple pendulum, infrared phototransistor, and Arduino board for calculating the gravitational acceleration (g). We used 13 pendulum lengths with five angles for each length to measure the period of motion. We found linear relationships between lengths and period-squared. The g-value was 9.806 ± 0.025 (average ± standard error) m/s2. Since this experiment set is cost-effective, and more straightforward method to understand, it will benefit the physics learning in educational institutions.

基于计算机的物理教学单摆实验装置的研制

摘要开发高性价比的物理实验设备是高校物理教学的必要条件。我们的目标是开发一个基于计算机的单摆实验装置，该实验装置由一个单摆、红外光电晶体管和用于计算重力加速度(g)的Arduino板组成。我们使用13个摆长，每个摆长有5个角度来测量运动周期。我们发现长度和周期的平方之间存在线性关系。g值为9.806±0.025(平均±标准误差)m/s2。由于该实验集性价比高，且更直观易懂，有利于教育机构的物理学习。
