The Improvement of Angular Acceleration Measurement in Rotational Rigid Body Inertia Experiment

Xing Li, Hongjian Huang

Abstract


In measurement of rigid body inertia by the falling body method, we obtain the angular acceleration through the angle
sensor measuring angular velocity, instead of photo gates measuring angular displacement. By using angle sensor, the formula of angular
acceleration becomes simple and the improved method has a result with higher accuracy.

Keywords


angular acceleration; rotation inertia; angle sensor
