The radius and mass of the moon are roughly 4 and 100 times smaller than those for earth, respectively. Based on this information, what might we expect the gravitational acceleration near the surface of the moon (gmon) to be?

radius of earth is 4 times larger than moon, mass of earth is 80 * Mass of moon. Given acceleration due to gravity at Earth's surface is 10m/s^2, how much iwll a 250 kg object weigh on the surface of the moon?
5. (Review) SInce the radius of the moon is much smaller than the radius of the earth, why isn't gravity stronger on the moon according to the inverse square law of Newton's law of Universal Gravitation? 6. What is the approximate value of the net centripetal acceleration experienced by a 75.0 kg astronaut located in the ISS, a distance of 254 miles from the earth's surface?
The mass of the moon is 7.34 × 1022 kg, and its radius is about 1.74 × 106 m (a) What is the value of “gmoon”, that is, the acceleration of gravity for a falling object near the surface of the moon? (b) What is the escape speed (from the moon) for an object on the surface of the moon? (c) What is the escape speed from the earth for an object that is as far from the earth as...
Find the center of mass of the Eath-moon system given: Radius of Earth = 6.37x10^6 Radius moon = 1.74x10^6 Distance between moon and Earth (centre to centre) = 3.82x10^8 Mass of earth = 81.5 times more massive than mass of moon.
A hypothetical planet has a mass 3 times that of the Earth and a radius twice that of the Earth. Calculate the value for acceleration due to gravity near the surface of this hypothetical planet.

Find the net, vector force on the earth. Sun Planet Alpha has a mass of 2.34 x 1025 kg and a radius of 5.67 x 107 m. What is the gravitational acceleration on the surface of the planet? a. What is the gravitational potential energy of an 891 kg object...
Mars has a mass of 6.421 × 1023kg, and radius 3.4 × 106m. (a) Calculate the gravitational acceleration “g”, at the surface of Mars. (b) Will the gravitational potential approximation given above for Mars be accurate over a larger or smaller range of values of ∆y than that for the Earth? Justify your answer (do the math). I already answered the question a, but I do not understand what they want for question b.
