(r can also be d) **Note: F is more sensitive to distance due to the inverse square law • F is inversely proportional to the square of the separation IMPORTANT: Mass of Moon = 7.4 x 10 22 kg Diameter of Moon = 1,700 km Mass of Earth = 6.0 x 10 24 kg Diameter of Earth = 6,400 km mM / mE = 0.012 rM / rE = 0.27...
