COLLOCATIONS FROM CORPUS
■ NOUN
attraction
▪ Their gravitational attraction would thus curve up the universe to infinitely small size.
▪ This hypothesis holds that giant tongues of material were torn from the preexisting Sun by the gravitational attraction ofa passing star.
▪ Stars are initially formed from gas, mostly hydrogen, and contract under their own gravitational attraction.
▪ By collision and gravitational attraction, the larger planetesimals swept up the smaller pieces and became the planets.
▪ Earlier experiments had compared the Earth's gravitational attraction with the centrifugal force from its own rotation.
▪ Both Earth and Moon have gravitational fields that allow bodies that would have missed them without their gravitational attraction to hit them.
▪ The hard core of Newtonian physics is comprised of Newton's laws of motion plus his law of gravitational attraction.
▪ Stars will remain stable like this for a long time, with heat from the nuclear reactions balancing the gravitational attraction.
collapse
▪ Then war intervened, Oppenheimer became involved in the atom bomb project, and he lost interest in gravitational collapse.
▪ It showed that gravitational collapse was not as much of a dead end as it had appeared to be.
▪ In 1965 I read about Penrose's theorem that any body undergoing gravitational collapse must eventually form a singularity.
▪ Let me go back to my earlier discussion of gravitational collapse.
▪ However, Chandrasekhar showed that for a sufficiently massive star the gravitational collapse continues until the star shrinks to a point.
▪ The no-hair theorem implies that a large amount of information is lost in a gravitational collapse.
▪ It modifies the scenario of gravitational collapse in the following way.
energy
▪ The more asymmetric the collapse, the larger the gravitational energy release becomes.
▪ For gravitational energy is negative, while rest mass and kinetic energy are positive.
▪ The answer is that it was borrowed from the gravitational energy of the universe.
▪ The universe has an enormous debt of negative gravitational energy, which exactly balances the positive energy of the matter.
▪ During the inflationary period the universe borrowed heavily from its gravitational energy to finance the creation of more matter.
▪ The debt of gravitational energy will not have to be paid until the end of the universe.
field
▪ As the star shrank, the gravitational field at the surface would become stronger and the escape velocity would increase.
▪ Thus, in particular, heavenly bodies moving in a gravitational field are well described by such geodesics.
▪ The rate of thermal escape depends on the temperature of the exosphere and on the gravitational field.
▪ Let us return to our sphere of particles dropping in a gravitational field.
▪ Thus, in a sense, the gravitational field has negative energy.
▪ Both Earth and Moon have gravitational fields that allow bodies that would have missed them without their gravitational attraction to hit them.
▪ To escape from the Moon's gravitational field, a sample must be accelerated to a velocity above 2.4 kilometres per second.
▪ All that is left is a strong, but invisible, gravitational field.
force
▪ Weight is the gravitational force of attraction exerted on a body.
▪ The split rock is slow to fall, the gravitational force being lower and the angle of fall correspondingly sharper.
▪ However, the larger the body the less important become its non-gravitational forces in comparison with its internal gravitational forces.
▪ This is because the gravitational forces are appreciable over much larger distances than the non-gravitational forces.
▪ He would be torn apart by the difference between the gravitational force on his head and his feet.
▪ But even with a rigid outer Moon gravitational forces would have raised the floor most of the way towards isostatic equilibrium.
▪ So for a sufficiently large number of matter particles, gravitational forces can dominate over all other forces.
▪ If there is less than a certain amount, the gravitational force will be insufficient to stop a never-ending expansion.
forces
▪ However, the larger the body the less important become its non-gravitational forces in comparison with its internal gravitational forces.
▪ This is because the gravitational forces are appreciable over much larger distances than the non-gravitational forces.
▪ Einstein next considered the implications of the equivalence principle for motion in free fall, that is to say motion under gravitational forces alone.
▪ But even with a rigid outer Moon gravitational forces would have raised the floor most of the way towards isostatic equilibrium.
▪ The gravitational forces are the manifestation of space-time curvature due to the presence of matter.
▪ So for a sufficiently large number of matter particles, gravitational forces can dominate over all other forces.
▪ They don't have the energy to hold themselves up any longer-against their own gravitational forces.
potential
▪ The metric components can also be rewritten in terms of the gravitational potential so that.
pull
▪ As they were collapsing, the gravitational pull of matter outside these regions might start them rotating slightly.
▪ After a while we are aware of a deviation, the gravitational pull of an unseen planet.
▪ Spring Tides - Moon and Sun in opposition, with combined gravitational pull. 4.
▪ As if this were an apex of this island, its source of gravitational pull.
▪ The complete system involved includes a flat surface - a table, perhaps - and a steady downward gravitational pull.
▪ Such a situation creates a gravitational pull toward contractual arrangements and a corresponding push away from employment in the traditional sense.
▪ What, even so, of the required gravitational pull?
▪ These counteract the tendency for the body to contract under its own gravitational pull.
wave
▪ In the alternative case of thick gravitational waves, they are non-scalar curvature singularities.
▪ It must be concluded that the above solution can not be interpreted in terms of an interaction between plane gravitational waves.
▪ Modern detectors which should be capable of detecting the gravitational waves from a supernova collapse in our Galaxy are described.
▪ It does not therefore describe the collision of genuinely non-aligned gravitational waves.
▪ It thus excludes situations involving impulsive gravitational waves.
▪ During the passage of gravitational waves it is the structure of space-time itself which oscillates.
▪ It is in fact a general feature of colliding electromagnetic plane waves that gravitational waves are always generated by the collision.
▪ A gravitational wave at the natural frequency for longitudinal oscillations of the bar would set it ringing like a tuning fork.
PHRASES FROM OTHER ENTRIES
magnetic/gravitational/force field
▪ All that is left is a strong, but invisible, gravitational field.
▪ All this occurs in magnetic fields very much above the maximum tolerated by the superconducting state.
▪ As the star shrank, the gravitational field at the surface would become stronger and the escape velocity would increase.
▪ At the upper critical field the magnetic field completely penetrated the sample and it reverted entirely to its normal state.
▪ In a few rare cases, lava flows on land have taken place just as the magnetic field was undergoing a reversal.
▪ It does raise the question of how pigeons detect the magnetic field.
▪ The flow of a magnetic field is taken from magnetic north pole to magnetic south pole.
▪ The radio waves, magnetic field and computer technology combine to produce vivid images of the body's soft tissue.
EXAMPLES FROM OTHER ENTRIES
▪ the Earth's gravitational pull
EXAMPLES FROM CORPUS
▪ A revealing difference between gravitational and electromagnetic radiation is that dipole radiation is absent in the gravitational case.
▪ However, it is not moving fast enough to totally escape the pull of the Earth's gravitational field.
▪ In practice instruments could not survive such a journey; they would be torn apart by the increasing gravitational field gradients.
▪ It modifies the scenario of gravitational collapse in the following way.
▪ Modern detectors which should be capable of detecting the gravitational waves from a supernova collapse in our Galaxy are described.
▪ The gravitational field generated in its productive phase by the legislative cycle attracted items from several diverse sources.
▪ The second main source of internal energy is heat from gravitational separation.
▪ They regard such wobbles as responses to the gravitational tugs of planets orbiting around them.
