1. | Just as linear momentum is the product of mass and velocity, so the angular momentum of a body is defined |
| 正如线性动量是质量和速度乘积一样,物体角动量也定义为其惯性矩和角速度的乘积。 |
|

2. | A falling object gains momentum as it falls. |
| 物体下落增进动量。 |

3. | The sledge gained momentum as it run down the hill |
| 雪橇从山上下冲时动量越来越大 |
|
|

4. | This can be determined, however, from momentum considerations, as will be explained in the next chapter |
| 但是,这可以由动量关系来确定,将于下一章介绍。 |

5. | The sledge gained momentum as it ran down the hill. |
| 雪橇从山上下冲时动量越来越大. |
|

6. | In motions of rotation angular momentum appears in much the same way as linear momentum appears in motion |
| 在旋转运动中的角动量产生的方式与平移运动中的线动量的产生是基本相似的。 |

7. | The truck gained momentum as it rolled down the steep road. |
| 卡车沿著陡峭的道路往下开时,冲力愈来愈大。 |

8. | Thus the energy developed by good fighting men is as the momentum of a round stone rolled down a mountain |
| 故善战人之势,如转圆石于千仞之山者,势也。 |
|

9. | We have found it necessary to represent momentum as an operator. |
| 我们已经发现需要用一个算符来表示动量。 |

10. | consistent debate about the number of English players performing for our top clubs has naturally gathered momentum |
