Gravitational forces keep us and everything on Earth stuck the ground and gives objects weight. Gravitational field strength varies on different planets. This means that while objects may have the same mass on wherever they are in the solar system, their weight can vary. The strength of gravity...
The gravitational force between two planets depends on their masses and _. A. the distance between their centers B. their surface areas C. their volumes D. their rotational speeds 相关知识点: 试题来源: 解析 A。解析:根据万有引力定律,两物体间的引力取决于它们的质量以及它们中心之间的距离。选项...
Some people believe that Earthquakes are more likely when the planets are all aligned. The table above gives some idea of the total gravitational force on the Earth from the planets. However, it doesn't tell us about the stresses the gravitational pull of the planets has on the material of ...
gravitational field - a field of force surrounding a body of finite mass field of force, force field, field - the space around a radiating body within which its electromagnetic oscillations can exert force on another similar body not in contact with it Based on WordNet 3.0, Farlex clipart co...
that opposes the self-attraction of matter has been proposed to explain the accelerated expansion of the universe.) Sir Isaac Newton was the first to fully recognize that the force holding any object to the earth is the same as the force holding the moon, the planets, and other heavenly bod...

There is a resemblance with the Lorentz force in electrodynamics. Consider therefore the Lorentz force acting on a point chargeq_{2}due to the fields from another moving point chargeq_{1}(i.e., an analogous two-particle problem as in Sect.2.3) ...
1. (General Physics) the force of attraction that bodies exert on one another as a result of their mass 2. (General Physics) any process or result caused by this interaction, such as the fall of a body to the surface of the earth Also called: gravity Collins English Dictionary – Comp...
What are the two planets without moons? What planet has 18 moons? A satellite orbiting the moon very near to the surface has a period of 110 minutes. What is free-fall on acceleration on the surface of the moon? Does the Sun have more gravitational force than Jupiter?
Harmonic models exist for the Earth, Moon, Mars, and other planets. A harmonic model is convenient because it gives an idea of how much influence higher-order terms have on the overall force. An Earth 68-by-68 spherical-harmonic gravity model is shown in Fig. 7.4. Sign in to download ...
