24、If a spacecraft travels faster than 11 km a second, it escapes the Earth'sgravitationalpull.(如果一架宇宙飞船飞行超过每秒11公里,它就能摆脱地球引力。) 25、As Europa orbits its planet, however, it flexes due to thegravitationaltug-of-war between it, its sister moons, and Jupiter.(然而...
5. Most planets around other stars have been found using a different method, measuring the tiny tugs that a planet makes on its sun's gravitational field. 6. Hawking responded that the gravitational pull of black holes was so strong, it unravelled the laws of quantum physics. ...
Related to Gravitational physics: Gravitational pull, Force of gravitygrav·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 called gravity. ...
Consequently, the acceleration of different bodies should be the same. This result means that the ratio of the gravitational mass to the inertial mass is the same for all bodies [as equation (6) indicates, the acceleration of a body in a given gravitational field depends on this ratio]: ...

What are the effects of distance and mass on the gravitational pull of the planets? How many moons would fit in the earth? What spacecraft used the gravitational pull of the planet Jupiter? What is the second law of gravitation? What is the acceleration due to gravity on Venus?
In his experiments with gravity, Isaac Newton showed how the motion of each planet in the solar system results from the combined gravitational pull of the Sun and of all the other planets, each contributing according to their mass and distance from the others....
Example 3: Gravitational Force at Different Altitudes Why does an astronaut on the International Space Station (ISS) experience less gravitational pull from the Earth compared to someone on the surface, and how does this affect the astronaut’s weight?
