| 1. | The viscous drags is equal to the resultant force .
粘阻力等于合力。 |
| 2. | In other words, zero resultant force is equivalent to no force at all .
换句话说，合力为零就相当于没有任何力的作用。 |
| 3. | The resultant force on the loop is evidently zero, since the forces on opposite sides are equal and opposite .
这一回线所受的合力显然为零，因为作用在相对两边上的力是等值而反向的。 |
| 4. | Using geometry , we shall be able to find out the resultant force
采用几何方法，我们就能求出其合力。 |
| 5. | There is no change in the motion of a body unless a resultant force is acting upon it
除非有一合力作用于物体上，否则物体的方向是不会发生变化的。 |
| 6. | All methods are related to each other , supplied each other , a effective control is their resultant force
