Lesson: Surface Gravity High School Physics

The International Space Station orbits Earth at a distance of 409 km above the surface. Earth has a mass of kg and a radius of 6,370 km. What is the local acceleration due to gravity at the height at which the International Space Station orbits? Give your answer to two decimal places.

Mars has a mass of kg and a radius of 3,390 km. What is the surface gravity of Mars as a ratio of the surface gravity of Earth? Use a value of 9.81 m/s² for the surface gravity of Earth. Give your answer to two decimal places.

Ganymede is the largest moon in the solar system, with a mass of kg and a radius of 2,630 km. What is the surface gravity on Ganymede? Give your answer to two decimal places.
