Using geometry, we shall be able to find out the resultant force.

采用几何法，我们就能求出其合力。

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。

Have the entire resultant force of certain sell an ability and certain team.

具备一定的销售能力和一定的团队整合力。

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。

If the direction is opposite with gravity, the resultant force is a levitation force.

若使合力总是指向重力的反方向，则这个合力是一种无支撑的悬浮力。
