SUMMARY
The gravitational acceleration at the International Space Station (ISS) is approximately 9.1 m/s², which is about 93% of the Earth's surface value of 9.81 m/s². To calculate the weight of a 72 kg astronaut at this altitude, the formula w = mg is used, where w is weight, m is mass, and g is gravitational acceleration. Thus, the weight of the astronaut at the ISS altitude is calculated as 72 kg * 9.1 m/s², resulting in approximately 655.2 N (Newtons).
PREREQUISITES
