gravity force

基本解释

Standard Force field - Behaves like a gravity force field.
标准的力场-像一个重力力磁场。
This is not centrifugal force keeping the Moon up, it's the anti-gravity force.
保持月球向上的不是离心力，而是反重力。
Both Planet X and the Earth are such magnets, but are not allowed to touch each other as the anti-gravity force keeps them apart.
行星和地球就是这种磁铁，它们是不能相互接触的，因为反重力的力量会使使它们分开。

Newton proved his idea by measuring how much gravity force would be needed to keep the moon orbiting the Earth.
Now, gravity, well force, is equal to mass times acceleration, g and the acceleration due to gravity is g.
是重力，等于质量乘以加速度，由重力导致的加速度是。

That is, you minimize potential energy and you see things falling under the force of gravity and so forthgoing to potential energy minima in conformance with this result.
换句话说，你使得势能最小化,然后发现我们关注的东西,在重力或者其他力的作用下下落,直到势能最小的地方,这和我们刚才的结果是一致的。
