Gravity keeps the moon where it's supposed to be — in orbit. Peepo / Getty Images Gravity is a force that we experience every day, yet it remains somewhat of a mystery. It's the reason we stay grounded on Earth and why objects fall when dropped. Although there are several theories ...
Deep within a nucleon, which is the stronger force between two quarks, gravity or the weak force? Why do you think so?Quark:A quark is an elementary particle and a basic component of matter. Protons and neutrons, the particles that make up the...

I came up with a mass of 0.62 micrograms (or the mass of 0.37 billion billion protons, yes that's two billions I wrote) to equate to 1/3 of the electron charge. I think this is what people mean when they say that gravity is a very weak force. EDIT: Oops, I slipped a decimal ...
1. The Moon's gravity is much ___(weak) than the Earth's. 相关知识点: 试题来源: 解析 【答案】weaker【核心短语/词汇】than:比【翻译】月球的引力比地球的引力小得多。【解析】than:比,后面接比较的对象,可知此空要用形容词的比较级,weak的比较级为weaker,much放在比较级的前面,加深程度,故答案为:...
【答案】so;around【核心短语/词汇】gravity重力;float漂浮【翻译】在太空里重力很弱,所以我们全都将在宇宙飞船里四处漂浮。【解析】根据句意,“在太空里重力很弱,所以我们全都将在宇宙飞船里四处漂浮。”,前后句为因果关系,故第一个空填so,为连词,表示“因此”。第二个空,修饰动词float,应填副词,结合句意,可...
Gravity is the weakest of the four fundamental forces of nature; the others are Weak Nuclear, Strong Nuclear and Electromagnetic. Gravity keeps us on the ground rather than floating in the air.
Let's leave aside electromagnetism and the strong nuclear force and just compare gravity to its "nearest" rival, the weak nuclear force. Perhaps if we can answer why the weak nuclear force is so impressively stronger than gravity, we can understand the whole picture. ...
Gravity is one of thefour fundamental forcesin the universe, alongside electromagnetism and the strong and weak nuclear forces. Despite being all-pervasive and important for keeping our feet from flying off theEarth, gravity remains, in large part, a puzzle to scientists. ...
Gravity in space is quite weak, (8) ___ we will float around in the spaceship. We will sleep in sleeping bags. In order not to float away in our sleep, we need to tie (9) ___ (they) to the wall. Even worse, our bodies may get weak because (10) ___ the low gravity...
