Unformatted text preview: where: F is the magnitude of the gravitational force between the two point masses, G is the gravitational constant (Newtons), m 1 is the mass of the first point mass, m 2 is the mass of the second point mass, and r is the distance between the two point masses. (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...
