基于Tracker软件的马格努斯滑翔机运动分析

Analysis on the Motion of Magnus Glider Based on Tracker Soft

利用Tracker视频分析软件对马格努斯滑翔机的轨迹进行描述,并通过逐帧分析确定滑翔机角速度随时间演化的关系式,进而通过建立理论模型推导出滑翔机的轨迹公式,使得不易直接测量的动态数据更加可操纵和量化;手机、数码设备的普遍化使得学生能够随时随地拍视频,Tracker软件给学生的物理实验研究带来了便利.

This manuscript describes Magnus glider trajectory by using Tracker （a video analysis software）, and finds out the relation of the glider angular velocity evolving with time through the frame by frame analysis , then deduces glider trajectory formula through the establishment of theoretical model, which makes the dynamic data that is difficult to measure directly be manipulated and quantitative; Mobile digital devices of generalization enables the students to shoot video at what time and under what circumstances, Accordingly, Tracker brings facilitation students to do physical experiment research.
