| 1. | We are interested in determining the amount of linear momentum delivered to the electron by the field .
我们对确定场传递给电子的线性动量的大小感兴趣。 |
| 2. | In other words, the vertical component of its linear momentum remains zero, since there is no resultant vertical force .
换句话说，因为没有竖直方向的合力，所以线动量的竖直方向仍为零。 |
| 3. | Principle of linear momentum
线性动量定理 |
| 4. | This should obviously violate the laws of conservation of linear momentum and energy
很显然，这违反了线性动量和能量守恒定律。 |
| 5. | In motions of rotation angular momentum appears in much the same way as linear momentum appears in motion of translation
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。 |
| 6. | Just as linear momentum is the product of mass and velocity , so the angular momentum of a body is defined as the product of its moment of inertia and its angular velocity
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。 |
| 7. | In order to form a stroke pattern mentioned above , i ' m assuming you ' ve moved into the ball with four steps ( steps 1 , 2 ) to place the contact between the width of the feet ( step 3 ) and transfer power with linear momentum ( step 4 ) while keeping centered and balanced ( step 5 )
为了形成上面提到的击球模式,我假定你是使用4步法移动接近球(第1 , 2课内容) ,击球点在两脚宽度之内(第3课) ,使用的是线动量(第4课) ,同时保持身体的重心和平衡(第5课) |
