摘要
通过Tracker软件的自动追踪功能描绘牛顿摆的运动轨迹,得到牛顿摆运动过程中的位移与动量变化图像,由此分析牛顿摆运动过程中的周期变化特点、轨迹特点以及动量衰减过程.本实验能够定量分析牛顿摆的运动特点,实验过程直观、高效,实验结果具有科学性,对物理教学有一定的参考价值.
Through the automatic tracking function of Tracker software,the motion trajectory of Newton pendulum is described,and the displacement and momentum change curve are depicted.On this basis,the periodic variation characteristics,trajectory characteristics and the process of momentum attenuation are analyzed.Not only this experiment can quantitatively analyze the motion characteristics of Newton pendulum,but also the experimental process is intuitive and the experimental results are scientific.Therefore this experiment has a certain reference value for physics teaching.
