The Influence of Monocycloid Curve Elasticity on the Results of Gravity Acceleration Measurement in University General Mechanics Experiments

文章尝试通过不同材料的摆线来改变单摆的弹性,以研究大学普通力学实验中摆线的弹性对重力加速度测量结果的影响,同时通过多线验证探究了摆长对重力加速度不确定度的影响,相关结果在提高实验教师对单摆运动理解、把控学生探索数据的正确性方面具有一定的意义.

In this article,we changed the elasticity of the cycloid of a single pendulum by using the cycloid of different materials,aiming to study the influence of the elasticity of the cycloid on the measurement results of acceleration of gravity in the university general mechanics experiment,At the same time,the effect of the length of the pendulum on the uncertainty of the acceleration of gravity was also explored through multi-line verification.The related results have certain significance in improving the experimental teachers′understanding of pendulum movement and controlling the correctness of students′exploration data.
