gravity force

基本解释

Standard Force field - Behaves like a gravity force field.
標準的力場-像一個重力力磁場。
This is not centrifugal force keeping the Moon up, it's the anti-gravity force.
保持月球曏上的不是離心力，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.
行星和地球就是這種磁鉄，它們是不能相互接觸的，因爲反重力的力量會使使它們分開。

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，等於質量乘以加速度，由重力導致的加速度是。

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.
換句話說，你使得勢能最小化,然後發現我們關注的東西,在重力或者其他力的作用下下落,直到勢能最小的地方,這和我們剛才的結果是一致的。
