单词	gravitation
释义	gravitationgrav‧i‧ta‧tion /ˌɡrævɪˈteɪʃən/ noun [uncountable] Examples EXAMPLES FROM THE CORPUS Another major contribution by Newton was of course his law of gravitation. However, the parallel between a linear acceleration and gravitation is conceptually simpler. Isaac Newton solved the final problem in the Copernican hypothesis by demonstrating that planetary motion was caused by gravitation. It is interesting to contrast gravitation with the other long-range force of nature - electromagnetism. It sounds almost like an adumbration of gravitation. Newton worried about that when his theory of gravitation required apparently instantaneous interaction between two distant objects. One example of a crucial event was the discovery of universal gravitation by Sir Isaac Newton in 1687. There was now a universal law of gravitation. word sets WORD SETS► Physics aether, nounamplitude, nounantimatter, nounantiparticle, nounastrophysics, nounatom, nounatomic, adjectiveattract, verbattraction, nounballistics, nounbeam, nounblack hole, nounbuoyancy, nouncalorie, nouncalorific, adjectivecapillary action, nouncathode ray tube, nouncentre of gravity, nouncentrifugal force, nouncentrifuge, nouncentripetal force, nounchain reaction, nouncondensation, nounconduct, verbconduction, nounconductive, adjectiveconductor, nounconvect, verbconvection, nouncore, nouncritical mass, noundemagnetize, verbdense, adjectivedensity, noundisplacement, noundynamic, adjectiveelectron, nounelementary particle, nounfallout, nounfissile, adjectivefission, nounfocus, verbfrequency, nounfriction, nounfusion, noungamma ray, noungravitation, noungravitational, adjectivegravity, nounhalf-life, nounhertz, nounhydraulic, adjectiveHz, imaging, nounimpetus, nouninertia, nouninvariable, adjectiveion, nounionize, verbkinetic, adjectivelaser, nounlift, nounliquefaction, nounliquefy, verblodestone, nounmagnet, nounmagnetic, adjectivemagnetic field, nounmagnetism, nounmagnetize, verbmass, nounmechanical, adjectivemedium, nounmeltdown, nounmomentum, nounmotive, adjectivemushroom cloud, nounnatural philosophy, nounneutron, nounNewtonian, adjectivenuclear, adjectivenuclear fission, nounnuclear fusion, nounnuclear physics, nounnuclear reactor, nounnucleus, nounoptical fibre, nounparticle accelerator, nounparticle physics, nounphonic, adjectivephosphorescence, nounphosphorescent, adjectivephoto-, prefixphoton, nounphotosensitive, adjectivephotosensitize, verbphysical, adjectivephysicist, nounphysics, nounpivot, nounpolar, adjectivepole, nounpotential energy, nounpower, nounpressure, nounpropulsion, nounproton, nounpull, nounquantum mechanics, nounquantum theory, nounquark, nounradiate, verbradiation, nounradio wave, nounray, nounreaction, nounreactor, nounreflect, verbreflector, nounrefract, verbrelativity, nounrepel, verbrepulsion, nounrepulsive, adjectiveresilience, nounresilient, adjectiveresistance, nounresonance, nounretention, nounsolid-state, adjectivesonic, adjectivesonic boom, nounsound wave, nounspace, nounspecific gravity, nounspectral, adjectivespectroscope, nounspectrum, nounstatics, nounsteady state theory, nounstrain, nounstress, nounsurface tension, nountension, nounthermodynamics, nounthrust, nountraction, nountrajectory, nountransmit, verbultrasonic, adjectiveultrasound, nounvacuum, nounvaporize, verbvapour, nounvector, nounwave, nounwavelength, nounwork, noun technical the force that causes two objects such as planets to move towards each other because of their mass → gravity:  Newton’s law of gravitation
