| 摘 要： | 研制了多功能球-球碰撞实验仪,利用该仪器对三组碰撞实验的研究发现,未退火小球和未退火小球碰撞可近似为弹性碰撞,其恢复系数为0.96;未退火小球和退火小球、退火小球和退火小球之间的碰撞为非弹性碰撞。本实验源自生活中的打靶实验,将其进行改造升级为物理实验中的研究性设计性实验,在启发学生创新思维和培养学生发散思考方面具有显著作用。

Development of the Two Balls Collision Each Other Multifunctional Instrument |

| Abstract: | Two balls collision each other multifunctional instrument has been developed. Three-group collision experiments have been studied. Two annealing balls collision can approximate elastic collision and the restitution coefficient is 0.96. The annealing ball and the un-annealing ball collision is inelastic collision. Two un-annealing balls collision is also inelastic collision.This experiment comes from target test of life,which is upgraded as the research experiment.Two balls collision experiment has a significant role to enlighten students' innovative idea and culture students' divergent thinking. |
