Question

The mass of earth is 5.98×10^27 g and the mass of the moon is 7.36 ×10^25 g.what is the sum of the mases of the earth and the moon?

Answer 1

The acceleration due to gravity on the surface of the Moon is about 1.625 m/s2, about 16.6% that on Earth's surface or 0.16 ɡ. Over the entire surface, the variation in gravitational acceleration is about 0.0253 m/s2(1.6% of the acceleration due to gravity)
