Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earthâmoon (center-to-center) distance is 3.82 Ă 10^8 m, earth's radius is 6.37 Ă 10^6 m, moon's mass is 7.36 Ă 10^22 kg, and earth's mass is 5.98 Ă 10^24 kg.
