摘要

-演示自由落体高度位移与时间关系的常规设置包括使用第二个计数器和米尺测量变量。这样的设置需要对一系列有规则的、连续的高度增量进行重复实验,同时记录每次坠落的时间。在混合环境中测量高度和时间在物理上是不可能实现远程学习的。本文中描述的设置,结合了树莓派微型计算机上的对象跟踪和数据记录程序的使用,以代替物理测量。该简易装置产生了传统的XY绘图仪,验证了高度位移与时间变量之间的关系,验证了该装置在混合教学实验室中的准确性和适用性。

Visualizing Free-falling Motion using Raspberry Pi Microcomputer for Hybrid Teaching Physics Laboratory
- A conventional setup to demonstrate the relationship of height displacement and time for a free-falling object includes the measuring of variables using a second counter and a metre ruler. Such a setup requires the experiment to be repeated for a series of regular, consecutive increments of height while the time for each fall is recorded. To perform the act of measuring height and time in a hybrid setting is not physically possible for remote learning. The setup described in this paper, incorporates the use of object tracking and data logging programmes on the Raspberry Pi microcomputer in place of physical measurements. The improvised setup yields the conventional XY plotter that verifies the relationship between height displacement and time variables, confirming the accuracy and applicability of the setup for a hybrid teaching laboratory.
