| 摘 要： | 本文阐述了溜溜球的力学原理，并对其运动过程进行了系统的理论分析，从中得出其平均动力为匀变速垂直运动，转动是均变速运动。若考虑到转向时平动动能的损失及空气阻尼和细胞麻擦阻力的作用损失的机械能，实际操作中需要及时给予补充。

| Abstract: | In the paper, we expound the mechanical principle of a yo-yo and analyze the process of its motion by systematic theory. We conclude that its translation is the perpendicular rectilinear motion with constant angular acceleration,its rotation is the one with constant acceleration. Considering the losses of kinetic energy of the translation when the change of rotator direction happens, the loss of mechanical energy of air damping and of the friction between strings and the yo-yo, the supplement needs to be given during the practical operation. |
