Three differentcalculation methodsare available for calculating the midpoint, each of which is useful in different situations. There arereasons for choosingone method over another. How the calculator works The calculator calculates the geographic midpoint based on the assumption of a spherical earth. ...
A 2,000-kg spacecraft is blasting away from the surface of an unknown planet the same size as the Earth. At 1500km above the surface, an instrument onboard reads the gravitational force to be 18000 N. What is the planet's mass?
no, the value of g is different at different places on the surface of the earth. the acceleration due to gravity is smaller at the equator than at the poles. this is because g is inversely proportional to the radius and the radius of the earth is smaller at poles and larger at the ...
Sorry but, I can’t agree. Based on the calculator I linked above, which you may find a problem with though I haven’t, even a 1-pound item (weighed on Earth’s surface) on the ISS would have an almost 3-pound gravitational force at 1-mm away from ...
