| 1. | In many cases an overall drag coefficient is given so that the net force on the surface can be determined .
在许多情况下，总的拖曳系数是已知的，因而可以确定作用于表面上的净力值。 |
| 2. | The direction of the acceleration is the direction of the net force
加速度的方向与合力的方向相同。 |
| 3. | The increment in momentum of a particle is equal to the impulse delivered ( 供给 ） by the net force
粒子动量的增量等于作用于它的力的冲量。 |
| 4. | Despite the large uncertainties , there is evidence that this estimated net forcing is approximately correct
尽管不确定性高，但有证据显示此估计值大致上是正确的。 |
| 5. | The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass
物体的加速度与所受的合外力成正比，与物体的质量成反比。 |
| 6. | An object at rest or traveling in uniform motion will remain at rest or traveling in uniform motion unless acted upon by a net force
所有物体在没有受到力的作用的时分，总坚持静止状态或匀速直线活动状态。 |
| 7. | It has been studied quite extensively in the past . when the rotor vibrating , a net force is exerted on fluid field , which will change the rotor ' s vibration on the same time
转子与润滑油膜的关系可以概括为“相互影响，相互制约” ，转子的运动会改变润滑流场情况，润滑流场的改变又反作用于转子。 |
| 8. | The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force , in the same direction as the net force , and inversely proportional to the mass of the object
牛顿第一定律：任何物体都保持静止或匀速直线运动的状态，直到受到其它物体的作用力迫使它改变这种状态为止。 |
