摘要

使用智能手机等现代实验工具进行课堂实验越来越受欢迎。因此，本研究进行了一项对比实验，利用简单的材料和声音传感器来确定自由落体和抛射体运动中重力引起的加速度值。在该实验中，自由落体和抛射体运动的高度与下落时间平方之间的关系用回归模型来表示。值得注意的是，自由落体和抛射体运动中 g 的实验值接近公认的重力加速度值。

Comparative experiment using free fall and projectile motions in determining the acceleration due to gravitational force

Classroom experiments using modern experimental tools like smartphones are in growing popularity. Hence, this study conducted a comparative experiment to determine the acceleration values due to gravitational force in free fall and projectile motions using simple materials and the sound sensor. In this experiment, the relationship between the height and the time squared of the fall in both free fall and projectile motions is represented in regression model. Notably, experimental values for g for free fall and projectile motions are close to the accepted acceleration value due to gravitational force.

期刊介绍： Physics Education seeks to serve the physics teaching community and we welcome contributions from teachers. We seek to support the teaching of physics to students aged 11 up to introductory undergraduate level. We aim to provide professional development and support for teachers of physics around the world by providing: a forum for practising teachers to make an active contribution to the physics teaching community; knowledge updates in physics, educational research and relevant wider curriculum developments; and strategies for teaching and classroom management that will engage and motivate students.
