| 摘 要： | 分析了小球在斜槽内横向作非简谐阻尼振动同时又在其纵向作匀加速直线运动的轨迹的理论公式.让粘满碳粉的小球在铺有坐标纸的斜槽内运动,记录真实运动轨迹,从实验图像中可以看出振幅越来越小、波长越来越长,这与理论分析相符.

| Abstract: | The motion formulae of small ball moving in a slope trough are obtained,which displays a composition of a transverse non-harmonic vibration and a longitudinal uniformly accelerated motion.In the experiment,the small ball covered with carbon powder is moving in a slope trough with coordinating paper inside,thus the motion trace can be recorded.The experimental graph shows that the wavelength increases with the decreasing amplitude,as given by theoretical analysis. |
