What is gravitational force? A. The force that repels objects. B. The force that makes objects transparent. C. The force that attracts objects towards each other. D. The force that makes objects glow. 相关知识点: 试题来源: 解析 C。解析:文章明确指出重力是吸引物体相互靠近的力。A 选项排斥...
. body is ,the greater is its force of gravity一个身体越大,越重的是它的引力 . It circles the Earth and is therefore know as a satellite of the Earth它绕地球转,因此知道作为地球的卫星 . To get out into space we have to overcome the Earth’s gravitational pull要进入太空,我们必须克服...
1 1.The gravitational force___an object at the Earth’s surface is called the weight of the object A.being acted on B acting on C having acted on D to act on Gravitational 重力的 我觉得是选D的吧,是要求不定式做宾语补语 但答案怎么是B呢 再说了 force后面能跟动名词么?(求ACD不能选的原...
The gravitational force would be described as a force of attraction (attractive force) that attracts all physical forms having mass. It is by far the weakest recognized natural force. Mathematical representation Mathematically, gravitational force can be represented as: F=Gm1m2r2 Here, F is the gr...
In physics, the weight of an object is the gravitational force with which Earth attracts it; ___, if a man weighs 150 pounds, this means that Earth pulls him down with a force of 150 pounds.在物理学中,物体的重量是地球吸引它的引力;___,如果一个人重150磅,这意味着地球以150磅的力把他...
The gravitational force between two objects is inversely proportional to the ___ of the distance between them. A. square B. cube C. square root D. cube root 相关知识点: 试题来源: 解析 A。本题考查万有引力定律中引力与距离的关系。引力与距离的平方成反比,所以答案是 A 选项的“square(...
The gravitational force is assumed to be mediated by spin 2 gravitons which are composed of four spin 1/2 (sub-) fermions. The dynamics is governed by a nonlinear spinorfield equation with nonperturbative Pauli-Villars regularization and canonical quantization. On the quantum level the fermion ...
1.问的是两个物体问的引力,与两个带电电荷间的electric force 的相同与不同.其实就是想要你去比较两条公式. solution: according to Newton's law of universal gravitation,gravitational force bewtwwn two massive objects F= G(M1M2/r^2) according to Coulomb's law,which describes the interaction of...
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...
Each system in the galaxy, and presumably, the universe, has a barycenter. The push and pull of the gravitational force of the objects is what keeps everything in space from crashing into one another. We have written many articles about gravitational force for Universe Today. Here’s an arti...
