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 ...
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 ...
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. ...
The strong force is one of the four fundamental forces of nature. Learn how it fits into the Standard Model of particle physics.
Weak and strong sources of gravity: An SO(1,3)-gauge theory of gravity The structural and dynamical elements of the Lorentz-Yang-Mills gauge theory of gravity are explained and analyzed. This theory is a generalized metric the... Camenzind,M. - Phys. Rev., D; (United States) 被引量:...

Gravity can be described in a variety of ways. Here's how Newton and Einstein took gravity from an observation to a measurable phenomenon.
Gravity is an attractive force between any two objects that have mass. The strength of the gravitational force depends on two factors: the amount of mass and the distance between the objects. It is one of the four fundamental forces, the other three being electromagnetic, strong, and weak for...
正确答案:B解析:利用题干句中的特征词Sun’s gravity及plasma共同作为线索,在文章第一段中找到相关信息。第二句意为太阳表面高温、多风,气候变化异常活跃,这使得太阳的引力无法控制住其大气层。第三句意为能量以带电粒子流的形式高速远离太阳表面。第四句说这种被称为等离子体的粒子流就是来自太阳的太阳风暴。可见...
