单词	escape velocity
释义	escape velocityesˈcape veˌlocity noun [countable, uncountable] Examples EXAMPLES FROM THE CORPUS A significant fraction of their water content can emerge from the explosion at a speed below the escape velocity of Mercury. As the radius of the star is reduced the escape velocity increases until eventually it reaches the velocity of light. As the star shrank, the gravitational field at the surface would become stronger and the escape velocity would increase. Even modest-sized impactors can blast atmospheric gases off of Mars at speeds above escape velocity. In fact, it is traveling well above escape velocity. Jupiter is a very massive planet, and its escape velocity is correspondingly high. Some of the gases from the explosion and fireball may reach escape velocity. This critical speed is called the escape velocity. word sets WORD SETS► Astronomy asteroid, nounastro-, prefixastronaut, nounastronomical, adjectiveastronomy, nounastrophysics, nounAU, aurora borealis, nounBig Bang, the, nounblack hole, nouncelestial, adjectivecomet, nounconstellation, nouncorona, nouncosmic, adjectivecosmic ray, nouncosmology, nouncosmonaut, noundead, adjectiveearth, nouneclipse, nouneclipse, verbecliptic, nounequinox, nounescape velocity, nounextraterrestrial, adjectivegalactic, adjectivegalaxy, noungeostationary orbit, nounHubble Space Telescope, the, infinity, nounintergalactic, adjectiveinterplanetary, adjectiveinterstellar, adjectiveJupiter, nounlaunch, verblaunch, nounlight year, nounLittle Bear, lunar, adjectivelunar month, nounmagnitude, nounMars, nounMercury, nounmeteor, nounmeteoric, adjectivemeteorite, nounMilky Way, the, month, nounmoon, nounmorning star, nounNASA, nounnebula, nounNeptune, nounnew moon, nounnova, nounobservatory, nounorbit, verborbit, nounorbiter, nounouter space, nounphase, nounplanet, nounplanetarium, nounplasma, nounPluto, nounquadrant, nounquarter, nounquasar, nounradio telescope, nounring, nounrocket, nounsatellite, nounSaturn, nounsea, nounshooting star, nounsolar, adjectivesolar system, nounspace, nounspace capsule, nounspacecraft, nounspace probe, nounspaceship, nounspace shuttle, nounspace station, nounstar, nounstargazer, nounsteady state theory, nounstellar, adjectivesun, nounsunspot, nounsupernova, nountelescope, nountelescopic, adjectiveterrestrial, adjectiveUranus, nounVenus, nounwane, verbwax, verbwhite dwarf, nounworld, nounzenith, noun the speed at which a rocket must travel in order to get into space
