摘要
利用智能手机内置的压力传感器和温度传感器设计了一个新实验.通过测量相对海拔高度与气压的关系,通过线性拟合获得重力加速度.这种新的实验方法无需额外装置,且实验过程简单易行.
One experiment is designed by using the sensors in smartphone including pressure sensor,temperature sensor. The acceleration of gravity is obtained through linear fitting by measuring the relationship between relative altitude and air pressure. This new method needs not additional equipment and the experimental procedure is easy to do.
