摘 要:重力加速度是一个十分重要的物理量,准确测量不同地区的重力加速度在理论学习中具有重大意义。本文采用了单摆、气垫导轨、复摆三种实验方法测量重力加速度,然后通过实验测出数据,并对实验数据进行处理,得出的结果分别为: 、 、 。研究结果表明:将这三种实验结果与周口市重力加速度的理论值进行比较,单摆是实验误差最小的实验方法。31685 毕业论文关键词:重力加速度;测量方法;误差分析
Study on Measurement of the Gravitational Acceleration
Abstract: The acceleration of gravity is a very important physical quantity, The accurate measurement of acceleration of gravity in different regions is of great significance in the study of the theory. The simple pendulum, air cushion guide, compound pendulum three experimental methods of measuring acceleration of gravity, then through experiments and measured data, and the experimental data are obtained. The results are: , , . The results show that: Comparing experimental results in the three different methods with theoretical data on gravitational acceleration in Zhou Kou city, the simple pendulum is the best experimental method with less error among three methods.
Keywords: acceleration of gravity; measurement method; error analysis
