摘　　要：为探究向心加速度、角速度及转动半径之间的关系,结合Phyphox软件,取材日常生活中的自行车、脱水菜篮及转椅进行简易实验,并利用Origin软件的乘幂函数模型进行数据拟合,根据拟合公式直接得到向心加速度与角速度的平方成正比的结论,引导学生经历从原始数据到实验结论的完整思维过程,培养学生的科学思维和证据意识.In order to explore the relationship between centripetal acceleration,angular velocity and radius of rotation,combined with Phyphox software,a simple experiment is carried out based on bicycles,dehydrated vegetable baskets and swivel chairs in daily life,and the exponentiation function model of Origin software is used for data fitting,and the conclusion that the centripetal acceleration is proportional to the square of angular velocity is directly obtained according to the fitting formula,guiding students to experience the complete thinking process from raw data to experimental conclusions,and cultivating students′scientific thinking and evidence awareness.

关 键 词：Phyphox软件 ORIGIN软件 简易实验 向心加速度 角速度
