用Tracker视频跟踪软件分析运动物体加速度

Analysis of Acceleration of Moving Objects with Tracker Video Tracking Software

文章运用Tracker视频跟踪软件分析运动物体的影像视频,获得其时间-位移数据,结合Excel数据分析软件对所获取数据进行线性拟合,根据加速度、时间、位移的关系,求得斜面运动物体的加速度。利用家中随处可见的物品和Tracker等软件测量抽象的加速度,降低了数据探究的难度,增加了实验探究的自由度和趣味性。

In this paper, Tracker video tracking software was used to analyze the videos images of moving objects to obtain time displacement data. The obtained data were linearly fitted with Excel data analysis software. The acceleration of the moving object on the inclined plane was obtained according to the relationship between acceleration, time and displacement. Abstract acceleration can be measured by objects that can be seen everywhere in the home and software such as Tracker, which reduces the difficulty of data exploration and increases the freedom and interest of experimental exploration.
