11.   Astronomers can determine the details of the closer object by studying how its gravitational forces affect the light from the more distant one.

12.   A neutron star is one that has collapsed because of gravitational forces.

13.   According to McFadden, a combination of gravitational forces could have jolted one into a strange course around Jupiter.

14.   But as with Tatum, there was a rare feeling of velocity and sureness, of monumental runs containing the gravitational force of a falling redwood.

15.   But the unsettling gravitational forces from such large planets in close proximity could have cleared the neighborhood of smaller bodies.

16.   Elsewhere in the country, new roller coasters have gravitational forces, or G-forces, greater than what an astronaut experiences during liftoff.

17.   Even if you theoretically could balance an egg on that date because of the change in gravitational forces, it would fall over anyway, says Novick.

18.   Eventually, the squeezing causes the clouds of elemental particles to collapse in response to gravitational forces.

19.   He explained that materials can be electrically separated more easily in space because the gravitational forces are much lower.

20.   In addition to gravitational forces, pressure tides are caused, in part, by the absorption of sunlight by stratospheric ozone.
