基于视频分析验证两种常见模型的机械能守恒

The Conservation of Mechanical Energy of Two Common Models is Verified by Video Analysis

利用Tracker软件的自动追踪功能,分别对弹簧振子系统和定滑轮系统进行分析,得到两个系统中物体运动规律图象及其数据。在考虑弹簧与滑轮质量的情况下,验证系统机械能守恒。

The automatic tracking function of the Tracker software is used to analyze the spring vibration subsystem and the fixed pulley system,and obtain the motion picture and data of the object in the two systems.In consideration of the mass of spring and pulley,the conservation of mechanical energy of the system is verified.
