根据第一段:The mass of the object, the amount(数量 )of matter it is made of, does not change.可知选项D是正确答案。3、答案:D解析:根据句子:Have you ever wondered why the pull of gravitation on the moon is only1/6 of the pull on the earth?可知在没有去月球是是180磅,回来之后是165磅...
so does gravitational pull. Black holes, astronomical objects often seen in science fiction movies, are so massive that light can't escape them. A grain of salt's gravity is much smaller because it has less mass. Weight refers to the force an object's gravitational pull ...

This was the highest temperature ever measured (测量) on the planet Earth. The highest waterfall in the world is Angel Falls in Venezuela which drops from an amazing height of 3 212 feet. The waterfall drops over the edge of Auyantepui in the Canaima National Park. The gravitational pull ...
General relativity has passed all the experimental tests so far, but its applicability is expected to break down when [the] effects of quantum mechanics (the theory of the very small particles) should become dominant. General relativity and gravitational lensing ...
One may have heard that a vacuum is nothing—the absence of matter. Space is typically called a vacuum, but even it has minute material in the void that makes it a non-but-near-vacuum as a whole. On Earth, we can isolate a region and pull all the material out of it, thus achievin...
Diagram of the Lagrange points associated with the sun-Earth system.(Image credit: NASA / WMAP Science Team) Each pair of gravitational bodies has five Lagrange points. Let's take Earth and thesunas an example. The first Lagrange point, L1, is between Earth and the sun. The second Lagrang...
Then came the name brands:Kenmoreappliances,Lands’ Endclothing, and the unbeatableKenmore Directline. Sears wasn’t just selling items; they were creating the brands people swore by. Each brand had its gravitational pull, drawing consumers into the orbit of Sears stores and catalogs. It was sy...
Neither is the levitation effect achieved in 2007 by countering Casimir force, a quantum force that essentially causes objects to stick to one another -- a type of nanofriction [source: ScienceDaily]. Antigravity, on the other hand, involves lessening the effects of gravitational pull on an ...
