Abstract

研究開發了基於手機加速度感測器的豎直方向彈簧振子實驗。使手機隨著彈簧振子上下振動,利用手機加速度感測器軟體得到彈簧振子做簡諧振動以及阻尼振動的加速度變化圖像。通過分析簡諧振動加速度變化圖像得出彈簧勁度係數、重力加速度;通過分析阻尼振動加速度變化圖像得出彈簧振子做阻尼振動的加速度方程。
A physics experiment on spring oscillation using a mobile phone acceleration sensor is developed.The mobile phone is connected to a fixed end by a spring and oscillated after receiving an upward push. Acceleration graphs for the case of simple and damped harmonic oscillations are got. Results for the spring constant,acceleration due to gravity and a formula for damped harmonic oscillation are obtained according to the graphs. Copyright © 2015 中國物理學會.
