Earth gravitational field strength

WebThe International Space Station has a mass of 4.19 105 kg and orbits at a radius of 6.79 106 m from the center of Earth. Find (a) the gravitational force exerted by Earth on the space station, (b) the space stations gravitational potential energy, and (c) the weight of an 80.0-kg astronaut living inside the station. WebSep 16, 2024 · Between the poles of Earth and its equator the gravitational field strength varies since the Earth is not perfectly spherical. The measured value of g (and apparent weight) also vary because the Earth is spinning. 1. Taking the radius of the Earth to be 6.4 x 10^6 m, calculate the centripetal force on a 1 kg mass on the equator.
