改进恒力矩法测定刚体转动惯量
An Improved Constant Torque Method of Measuring the Rigid Body Moments of Inertia
摘要
Abstract
This paper focuses on the study of measurement of rigid body moment of inertia in specialized course of college physics. With the appropriate combination weights and cone radius,the system was carried out a decelera-tion movement and an acceleration movement,and the rigid body moment of inertia has been measured. With the improved method for measuring constant torque,the impact of variation of resisting moment according to the angular velocity was reduced,and the result was more accurate with smaller error.关键词
