The equation that describes this lab is: Gm m Fg = Notice that in the equation, ris squared AND it is on the bottom of a fraction. We therefore say that the relationship between Fg and ris an inverse square relationship. What this means is that: When rgets two times bigger. Fg becomes four times smaller than before. (Due to the square relationship, two becomes four; two squared is four. Due to the inverse relationship, when one variable gets bigger, the other does the opposite and gets smaller). If r is made three times smaller, Fg gets nine times bigger than before. Question to Answer If r was made four times bigger, explain what you'd expect to happen to Fg.
