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...
The gravitational force from the other planetsdoes slightly affect the Earth's orbit, but the gravitational pull from the other planets and the Moon is still very small. ... When they are closest to the Earth, Jupiter only exerts 0.0062% of this force and Mars only 0.00023%. Which planet ...
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 ...
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. ...
What is the gravitational force of the Sun on the Earth? The moon orbits around the Earth. If the moon stopped moving (v = 0 m/s), what would happen to the moon? What are the effects of distance and mass on the gravitational pull of the pla...
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. 选项: A、of all the other plan...
The Gravitational Slingshot The gravitational slingshot is a way that scientists have truly harnessed the gravitational pull of a planet by using it to...
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]: ...
