The gravitational force of the moon is one ten-millionth that of earth, but when you combine other forces such as the earth's centrifugal force created by its spin, you get tides. The sun's gravitational force on the earth is only 46 percent that of the moon.
If you were doing a block of text you would normally do double spacing and in this case, using same margins and same font you would get an average of 480 words, but with normal text the norm is usually around 300 words to a page. Not enough parameters to answer.
Contrary to what we said above, a one-page document these days will not likely hold 500 words on the page. Once headlines, imagery, and formatting are accounted for, a word-count of about 250 words will work much better in the space available.
