利用大学实验室常备器材和智能手机设计了一套实验装置,旨在实现科里奥利加速度的可视化与定量测量,以验证其理论关系式。该装置将智能手机固定于转盘上作为非惯性参考系,旋转拍摄在地面系中做匀速直线运动的光点,并用光电门测得光点在地面系中匀速直线运动的速度大小。通过Tracker处理智能手机拍摄的视频,描绘光点在非惯性系中的运动轨迹,将科里奥利力现象可视化,并获取各时刻质点的速度、加速度等物理量,将实验测得的加速度与根据科里奥利加速度公式2'×ω计算的理论值进行对比(其中ω为转盘角速度,v'为光点在惯性系中的速度)。实验数据与理论计算值吻合良好,定量验证了科里奥利加速度关系式。
Abstract：A demonstration and measurement device for Coriolis acceleration was designed using commonly available university laboratory equipment such as an air track, turntable, laser pointer, and a smartphone. This apparatus utilizes the turntable to rotate the smartphone, which captures the motion of a light spot moving uniformly in a straight line within the ground frame. This enables the observation and recording of the particle.s motion in the inertial frame from the perspective of the rotating non-inertial frame. The speed of the light spot.s uniform linear motion in the inertial frame is measured using a photogate. With the aid of Tracker for video analysis, the exact trajectory of the light spot in the non-inertial frame is plotted, visualizing the Coriolis force phenomenon. Furthermore, physical quantities such as the velocity and acceleration of the particle at various time points are obtained, allowing for a quantitative verification of the Coriolis acceleration relationship.
