Among them, the net migration of labor force and GDP rises is represented positive correlation, but initial net migration labor level and GDP rises is negatively correlation.

The more rapidly an airship ascends, the more severely its "super cold" condition becomes, and the more significantly the net static lift force reduces.

They can collide, they can cause fireworks, they can explode, they can break up in pieces, but momentum will be conserved in the absence of any net external force.

它们可以碰撞，可以燃烧，可以爆炸，可以成碎片，在没有外力的时候，动量可以守恒。

Kinetic energy can be destroyed, but momentum cannot be destroyed in the absence of a net external force on the system as a whole.

动能可以被毁，但是动量不能，在整个系统外力，不存在情况下。

And if there is no net external force on the system as a whole during the collisions, then momentum is conserved.

若没有外力，作用于系统整体，在碰撞过程中，动量就是守恒的。

互联网摘选

Momentum is conserved, because there was no net external force, so now kinetic energy is also conserved.

动量是守恒的，因为它不受外力，因此动能也是守恒的。

Whenever we have a system of objects with zero net external force, the momentum must be conserved.

无论什么时候，物体完全不受外力的时候，动量可以守恒。

And so one string must be pulling in this direction and the other string must be pulling in this direction so that the net force on the system is zero.

因此一条细绳施加一个拉力，朝这个方向，另一条细绳也必然施加拉力，朝这个方向，这样整个整体合力为零。

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。

The net force is ultimately the sum of the external force and all the internal forces.

合力是最终的总和，外力与所有内力总和。

互联网摘选

But the net force is zero.

合力为零的话。

If there had been a net force, then indeed it would also go down, if this force were larger than this.

如果没有净力，那就不会下降了，如果那个力大于这个。
