This chapter considers the gravitational field of the earth. The chapter mentions the forces acting on elementary volume of the rotating Earth in an inertial frame and considers the second Newton's law in non-inertial system. It introduces the centrifugal force and gravitational field, as well as...
The gravitational force of the Sun and the Moon upon Earth depends on ___. A. their size B. the depth of the oceans C. their weight D. their distance to E. arth 相关知识点: 试题来源: 解析 D 答案:D 解析:分析第三段可知,太阳和月亮对地球的引力与其和地球的距离有关。反馈...
Hence, it can be said that the gravity of the Moon is 5/6, or 83.33%, less than that of the Earth. Gravity Value and Gravitational Force It is well known that a person's weight on the Moon is one-sixth that on Earth. The explanation for this is that the gravitational force on th...
If the distance between the Earth and the Moon were to double, while the masses remained the same, the gravitational force would become ___. A. F/2 B. F/4 C. 2F D. 4F 相关知识点: 试题来源: 解析 B。引力与距离的平方成反比,距离变为 2 倍,引力变为原来的 1/4,答案是 B 选项...
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 is determined by the magnitude of the mass of the body in consideration times the constant value of gravity of Earth. Mathe... Learn more about this topic: Gravity Definition & Equation from Chapter 19/ Lesson 10 ...
Due to this gravitational force, the earth pulls any object towards its surface. Therefore, the direction of the weight of the object is towards the earth's center. Weight is a vector quantity.The weight of an object varies from place to place:...
(General Physics) the factor relating force to mass and distance in Newton's law of gravitation. It is a universal constant with the value 6.673 × 10–11 N m2 kg–2. Symbol: G Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 199...
What is the nature of gravitational force?Gravitational ForceThe gravitational force is the force of attraction between two bodies which is inversely proportional to the square of the distance between the bodies and directly proportional to the product of their masses....
The gravitational field at a point in space equals the gravitational force experienced by a test particle placed at that point divided by the mass of the test particle. Note that the presence of the test particle is not necessary for the filed to exist -- the Earth creates the gravitational...
