#4
Front (Question)

what is gravity?

Back (Answer)

the natural phenomenon by which all things with mass gravitate toward one another

when was the general theory of relativity proposed?

Back (Answer)

1915

#7
Front (Question)

what does the general theory of relativity describe?

Back (Answer)

describes gravity not as a force, but as a consequence of the spacetime caused by the uneven distribution of mass

what is the definition of 1G?

Back (Answer)

Earth’s gravity

#10
Front (Question)

what happens when Earth becomes close to alignment?

Back (Answer)

it becomes warped out of its orbits by the gravitational attraction which imparts 3 changes on the way in which the Earth is rotating

Back (Answer)

a wobbling spinning top

#12
Front (Question)

what is axial precession?
