On the Moon, astronauts experienced gravity which is less than they had known on Earth. Moon's mass is 0.012 (0.12 percent) of Earth's mass, and its radius is 0.27 times Earth's (27%). Therefore gravity on the Moon is only 0.16 or 16% of Earth's gravity. A falling object on the Moon accelerates at about 1.6 m/s2. If the Earth only had Moon's mass and still had its present size, how fast would a falling body on Earth accelerate? a. 82 m/s2 b. 0.12 m/s2 c. 1.6 m/s2 d. 9.8 m/s2

Provide evidence to support your observations using the gravitational values below.Gravitational Values for Select Planets Mercury: 3.7 m/s ^ 2 Venus: 8.9 m/s ^ 2 Mars: 3.7 m/s ^ 2 Neptune: 11.0 m/s ^ 2
Newtons version of Kepler's third law is P2=4pi2/(G(M1+M2)) x a3. Since the square of the period P varies inversely with the Sum of the masses (M1+M2), the period itself depends on the inverse square root of the object masses. If a solar system has a star that is 3.9 times as massive as our Sun, and if that solar system has Earths exact twin, what is the orbital period of that planets months ?
