论文摘要
纸条，例如五彩纸屑，在短时间后降落到地板上开始围绕水平轴旋转。与自由下落相比，这会减慢垂直速度，并增加水平速度分量。旋转频率，跌落角度和跌落速度似乎取决于纸条的尺寸和质量。可以描述该飞行的物理学，即运动，质心的翻译（能量分析，力分析，秋季速度V（b，h，m）的公式，秋季角度角度的公式（b，b，h，m）），围绕质心的旋转（频率f（b，h，h，m），旋转速度，频率的频率，旋转速度的频率和转换的范围和轮换的范围。
Paper strips, e.g. confetti, descending to the floor begin to rotate around the horizontal axis after a short time. This slows down the vertical velocity compared to free fall and adds a horizontal velocity component. The frequency of rotation, the angle of fall and the speed of fall seem to depend on the dimensions and mass of the paper strips. The physics of this flight can be described, i.e. the movement, the translation of the centroid (energy analysis, force analysis, formula for fall speed v(b,h,m), formula for angle of fall α(b,h,m)), the rotation around centroid (formula for frequency f(b,h,m), rotation speed), the flight path with the results from translation and rotation, the visualization of air turbulence and the loss of energy.
