| 摘 要： | 研究了短跑的“收尾速度”模型.在收尾速度模型中,收尾速度vm与过程特征参量k成反比,而过程特征参量k不是个人参量.在讨论变加速运动问题时,我们建议使用科学的规范用语,比如:急动度,力变率. |
| 关 键 词： | 变加速运动 短跑 收尾速度 急动度 力变率 |

| Abstract: | The terminal velocity model on short distance running is researched.The terminal velocity is inversely proportional to characteristic parameter on process in the terminal velocity model,but the characteristic parameter on process is not a parameter on individual character.When the questions on varying accelerated motion are discussed,we propose that the scientific normalized words such as jerk and time rate of force change are used. |
| Keywords: | varying acceleration motion short distance running terminal velocity jerk time rate of force change |
