摘要
制作了一只沙漏,通过拍摄视频,获得了用灵敏电子秤称量沙漏流沙过程中其重量随时间变化的规律。通过建立模型,分析了沙漏漏沙过程中其重量随时间变化的规律,理论曲线与实验曲线符合较好。
An hourglass was made, and the rule of its weight changing with time in the process of measuring quicksand with sensitive electronic scales was obtained by shooting video. Through the establishment of the model, the law of hourglass weight changing with time in the process of sand leakage is theoretically analyzed, and the theoretical curve is in good agreement with the experimental curve.
