The centripetal force that keeps the moon in its orbit around the earth is provided by the gravitational pull of the earth. This force accelerates the moon toward the earth at $2.7 \times 10^{-3} \mathrm{m} / \mathrm{s}^{2},$ so that the moon is continually "falling" toward the earth. How far does the moon fall toward the earth per second? Per year? Why doesn't the moon come closer and closer to the earth?
