It is the gravitational interaction with planets, right?───这是引力与行星的相互作用，对吧？
Its oscillation depends on the strength of the gravitational field.───它的摆动取决于重力场的力。
If a spacecraft travels faster than 11 km a second, it escapes the Earth's gravitational pull.───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。
And that was that the gravitational field, due to mass, will deflect not only the trajectory of particles, but will deflect light itself.───那就是由于有质量，引力场不仅会使粒子的运动轨迹偏转，而且会使光本身偏转。
So if I make a plot of the gravitational potential energy as a function of y, then I would get a straight line.───因此如果我画一张，重力势能，受y变化的图，那么会得到一条直线。
Light traveling through the matter clump is warped and distorted, a phenomenon called gravitational lensing.───当光线穿过这些物质团块的时候就会发生弯曲或扭转，这种现象被称为“引力透镜效应”。
If it had been slightly more dense, it might have undergone gravitational collapse, just like the matter falling into a black hole.───假如它的密度比临界密度再高一些，将会导致重力塌缩，就像掉入黑洞的物质一样。
Astronomers measure how much dark matter lies in galaxies by a fluke of physics called gravitational lensing.───天文学家通过一种叫做引力透镜效应的物理现象来测算星系中暗物质的质量。
Small moonquakes, originating several miles below the surface, are thought to be caused by the gravitational pull of the earth.───发源于月球表面以下几英里的微弱月震据估计是由地球引力的牵引造成的。
Further gravitational segregation of the iron core means that denser material moves inwards displacing less dense material outwards.
Tidal stress and gravitational asymmetries had pulled the sphere out of shape. Newtonian mechanics had done the rest.
It thus excludes situations involving impulsive gravitational waves.
What, even so, of the required gravitational pull?
The gravitational forces are the manifestation of space-time curvature due to the presence of matter.
In a gravitational field this causes the denser air to sink and buoy up the less dense gas.
All matter exerts a gravitational attraction.
There is also gravitational potential energy.
Here is a gravitational field device to draw down orbiting objects on to a preprogrammed landing site.
