摘　　要：自制了基于Arduino的向心力实验仪,通过控制变量法探究了向心力与轨道半径、角速度、质量的关系.利用滚珠丝杠式直线模组控制和测量轨道半径,利用力传感器配合小球套环测量向心力,利用光电传感器定位和测量角速度,利用蓝牙无线传输数据,测量数据动态显示并通过串口传入Excel进行处理.利用可调倾角底座,还可以研究倾斜平面和竖直平面内的匀速圆周运动.A centripetal force experiment instrument based on Arduino was developed,which was used to explore the factors affecting the magnitude of centripetal force.The track radius was controlled and measured by the ball-screw type linear module,the centripetal force was measured by the force sensor and the ball sleeve,position and angular velocity measurement was realized by the photoelectric sensor,and data were transmitted wirelessly by Bluetooth.The data was displayed dynamically and transferred to Excel through serial port for processing.By using the adjustable tilt base,it could also be extended to study the uniform circular motion in inclined or vertical plane.
