我们设计了一个简单的基于Arduino的实验来研究自由落体。在超声波距离传感器和Arduino板的帮助下,收集了与黄铜碟的自由和垂直下落运动相关的实验数据。然后绘制从不同初始高度获得的位置-时间曲线,并使用Excel实验确定重力加速度。
We have designed a simple Arduino-based experiment to study free fall. The experimental data associated to the free and vertical fall movement of a brass saucer are gathered with the help of an ultrasonic distance sensor and an Arduino board. The position–time curves obtained from different initial heights are then plotted and the acceleration of gravity is experimentally determined using Excel.
