摘要
在复摆实验中,利用智能手机中的角速度传感器和SensorKinetics软件,通过绘制复摆振动时的"角速度-时间"图像计算振动周期,进而测定当地重力加速度.
The angular velocity sensor and the SensorKinetics software of smart phone were used in the compound pendulum experiment. The vibration period of compound pendulum was calculated after plotting the velocity-time curve. Thus the local acceleration of gravity was confirmed.
