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
  • Understanding of gravitational acceleration and its variations at different altitudes
  • Familiarity with the formula for weight calculation (w = mg)
  • Basic knowledge of mass and its measurement in kilograms
  • Awareness of the concept of weight in Newtons
NEXT STEPS
  • Research the effects of altitude on gravitational acceleration
  • Learn about the physics of weightlessness in space environments
  • Explore the calculations involved in satellite dynamics
  • Investigate the differences in gravitational acceleration on other celestial bodies
USEFUL FOR

Students studying physics, educators teaching gravitational concepts, and anyone interested in the effects of altitude on weight and gravitational forces.

Homework Statement



The gravitational acceleration at the International Space Station’s altitude is about 93% of its surface value.

What’s the weight of a 72 kg astronaut at this altitude?

Homework Equations



w=mg
where w is weight
m is the mass
g is the gravity's acceleration

The Attempt at a Solution



mass is given as 72kg

I know the station is a satellite in space. but how do i go about finding acceleration? any tips would be helpful.

What's the 'surface value' of the acceleration due to gravity?

well i know acceleration due to gravity is 9.81 meters per second every second. Ah so that's what they are asking! I got it! =]
