SIMPLIFIED MEASUREMENT OF GRAVITY ACCELERATION BASED ON ELECTROMAGNETIC INDUCTION PRINCIPLE.
Journal Title: International Journal of Advanced Research (IJAR) - Year 2019, Vol 7, Issue 8
Abstract
There are many methods for measuring gravity acceleration in physics experiments. These methods require special experimental instruments.Based on electromagnetic induction principle, this paper introduces a method using free audio processing software to measure gravity acceleration. In this method, no special experimental equipment is needed, and students can even experiment at home. The relative error of local gravity acceleration is 0.3%. This method stimulates students\' interest in learning and enhances students\' thinking. It has positive significance with hands-on ability, and also enriches the measurement method of gravity acceleration.
