英文:The gravitational force between two objects depends on their masses and the distance between them. 中文:两个物体之间的引力取决于它们的质量和它们之间的距离。 英文:The moon's gravitational pull causes the tides on Earth. 中文:月球的引力造成了地球上的潮汐。 英文:Grav...
Launch vehicle: Rocket system that boosts a spacecraft into Earth orbit or beyond Earth's gravitational pull.运载火箭:将航天器推入绕地球轨道或脱离地球引力范围的火箭系统。 If the distance between two objects is shortened twice, then the gravitational pull grows by a factor of 4.如果两物体间距离...
Suppose that the gravitational force between two objects of mass M and m has a magnitude of KMm/r^3 (instead of GMm/r^2), where K is the gravitational constant. a) What would Kepler's third law for circular orbits be? b) How would the orbital period T of ...
(redirected from Gravitational pull)Also found in: Thesaurus, Medical, Encyclopedia. grav·i·ta·tion (grăv′ĭ-tā′shən) n. 1. Physics a. The natural phenomenon of attraction between physical objects with mass or energy; the weakest of the four fundamental forces of nature. Also...
of gravitational force. Newton's equation for universal gravitation states that the force of gravitational attraction between two objects is equal to a gravitational constant times the mass of the first object times the mass of the second, all divided by the square of the distance between them. ...
Earth's gravitational force or pull keeps us and everything else Earth from floating away to space. Try and work out the gravitational force between two objects in terms of a quantum graviton, however, and you quickly run into trouble—the answer to every calculation is infinity. Weight is ...
Gravitational force -an attractive force that exists between all objects withmass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two ...

This energy is associated with the state of separation (configuration) between two objects (ball and earth) attracted by gravitational force. Work and Potential energy In the above example, the work done by the gravitational force is negative if the ball is thrown up. As the ball rises, its...
Gravitational pull due to the Kuiper belt In this work we study the gravitational influence of the material extending from Uranus orbit to the Kuiper belt and beyond on objects moving within these regions. We conclude that a density distribution given by $ho(r)=\\frac{1}{r}$ (fo... de...
