摘要
Tracker软件是一种广泛使用的视频分析软件,通过分析物理实验视频,追踪研究对象的运动轨迹,以简洁、高效的数据分析手段揭示物理现象背后所隐藏的物理规律.利用Tracker软件分析了单摆测定重力加速度的实验视频,通过自动追踪摆球运动的轨迹,精确测得了单摆运动的周期和重力加速度.
Tracker , a kind of software that is widely used to analyze video, by which to analyze physical experimental video, trace the running track of the study object to discover the physical regularity that hind behind the physical phenomenon with brief and efficient data analyze approach. The paper analyzes experiment video of pendulum measuring Gravitational acceleration through Tracker software, by automatically tracing the track of pendulum ball movement, accurately measured the period and Gravitational acceleration of pendulum ball movement.
