Uncertainty Analysis on the Rotational Inertia Experiment of Rigid Body with Three-wire Pendulum

Wan Zhi-long

Abstract

Uncertainty is an important indicator to reflect the reliability of measurements in college physics experiment,but it is often ignored in teaching because of its difficult computational process.Through the rotational inertia experiment of rigid body with three-wire pendulum,this paper discussed systemically the uncertainty,and gave out computational methods.Furthermore,the sources of uncertainty were analyzed,and some improvement measures were offered.
