身体的力量把世界内部连接在一起,地球的引力,通常被称为重力。艾萨克·牛顿爵士描述第一次在他的万有引力定律。重力的原因之一是落在地上,一切都好像有了一个磁铁。人类和动物需要肌肉力量来克服它。飞机喷气发动机无视重力。没有强大的推力火箭,会有任何太空旅行。
重力的影响削弱了远从地球表面。结果是零重力或失重。科学一直梦想着人为影响甚至溶解重力。一种可能性是所谓的重力发生器。在它的中心有一个金属环。冷却温度零下260度,金属失去电阻。戒指就装在旋转时,其内部的电子顺利没有摩擦。这将创建一个重力力场,反对以或多或少的力量取决于旋转的速度。也许这是一种欺骗重力的影响?所有天体的重力影响,包括所有的行星和太阳和月亮。 It's a pulling force of equal strength in all directions that keeps things tidy in our solar system. It forces mass into a rounded form, similar to how a magnet would. This is why planets and stars have an almost spherical shape. But they are also shaped this way because they are or used to be made up of liquid in their interior. This is because in the zero gravity conditions of space, liquids always form a sphere under the pressure of their surface tension. On Earth, the influence of zero gravity can be demonstrated with the so-called drop tower experiment. To start with, a glass is filled with water, but enough space is left for air. The influence of various forces and the surface tension of the water presses the trapped air, not the water, into a spherical shape.
然而,因为他们在自己的轴旋转,大多数行星有些夷为平地。就像一个旋转的球,一个行星也改变了形状。这是一个原因在赤道直径大于两极之间。月球的引力潮汐负责。然而,地球的自转作为制动机制这一过程。长期的结果是,天变得越来越长。经常需要做改正以确保我们的时钟继续配合时间规定的太阳。这是用所谓的闰秒的插入。仍然,地球将继续旋转很长一段时间来和重力仍将是什么,力使世界最深处的内部。
