EARTHFLOWSThe semidiurnal (12.42h) and semimonthly (14.76days) lunar tides have been well-known by fishermen for several centuries. The gravitational force of the relative positions between the Sun, the Moon, an
The earth pulls on the moon with a gravitational force,and it is this force that in its orbit. 答案是keeps the moon 答案 地球依靠万有引力拉住月球,使它在自己的轨道上运行. 相关推荐 1 The earth pulls on the moon with a gravitational force,and it is this force that in its orbit. 答案...
The tides is the effect of the gravitational forces between the Earth and the Moon. A. single B. only interesting C. the most noticeable D. the most interesting()24. Which side of the Moon carries a stronger gravitational force? A. The side closest to the Earth B. The side farthest ...
: the gravitational attraction of the mass of the earth, the moon, or a planet for bodies at or near its surface (2) : a fundamental physical force that is responsible for interactions which occur because of mass between particles, between aggregations of matter (such as stars and planets...
where M is the mass of the Earth. If this formula is written P=mg, then g=GM/R2. The constant g is then called the acceleration due to gravity. It is the acceleration of free fall of a body in the Earth's gravitational field. At altitudes z such that the force of gravity may ...
1.5Gravitational force Thegravitational forceon a particle with mass ofmcan be calculated by F=mg Wheregis thegravitational accelerationof a theplanetary bodyor the asteroids. For the Earth, Moon and Mars,gis equal to 9.86m/s2, 1.6m/s2, and 3.7m/s2, respectively. ...
How does the gravitational pull of the moon affect the Earth?相关知识点: 试题来源: 解析 潮汐形成、地球自转减速、地壳轻微形变 月球的引力对地球的影响主要体现在以下几个方面: 1. **潮汐现象**:月球引力对地球各点产生的差异引力形成潮汐力,导致海水周期性涨落(潮汐),主要出现在海洋中; 2. **地球自转...
1. Uh...a moon in such a complex system, is not only affected by the gravitational force of the planet, but also by that of the other moons.(Official53-L4) 嗯...卫星在这个复杂的系统中,不仅被土星的重力影响,而且还被其他卫星的重力所影响。 2. Well, by tidal force, I'm referring to...
Gravity allows all objects to stay firmly on the ground. Oceanic tides are formed due to the force of gravity of the moon and the sun on the surface of the water. The gravity of the earth holds the atmosphere on the earth. The force of gravity causes raindrops to fall on the surface ...
The gravitational force exerted by the Sun on the Moon is about twice as great as the gravitational force exerted by the earth on the Moon, but still Moon is not escaping from the gravitational influence of the earth. Mark the option which correctly explains the above system. ...
