SUMMARY

The discussion focuses on calculating the gravitational force experienced by astronauts at an altitude of 500 kilometers above Earth's surface. The formula used is gr = (R²/r²) × g, where R is Earth's radius and r is the distance from the center of the Earth to the astronauts. The user calculated a gravitational force of approximately 9.09 m/s², which is indeed a valid calculation, but the result should be expressed in terms of g's for clarity. The correct interpretation of the result is essential for understanding the reduced gravity experienced in space.

PREREQUISITES
  • Understanding of gravitational force and its calculation
  • Familiarity with the formula g = G.M/R²
  • Basic knowledge of units of measurement in physics
  • Concept of gravitational acceleration at different altitudes
NEXT STEPS
  • Learn how to convert gravitational acceleration to g's for various altitudes
  • Explore the impact of altitude on gravitational force on other planets
  • Study the implications of reduced gravity on human physiology during space travel
  • Investigate the use of gravitational equations in aerospace engineering
USEFUL FOR

Students in physics, aerospace engineers, and anyone interested in the effects of gravity on astronauts in space.

So, how much weaker is the force of gravity at 500 kilometers above Earth's surface? Calculate how much of a g force the astronauts are actually experiencing. This equation can be modified for any other planet by replacing using the planet's radius and its surface gravity (how many g's).

this is the problem

The equation they gave me was:
gr=R(squared)/r(squared) X(times) g

I got:
gr=(6378.1km(squared)/6878.1km(squared) X(times) 9.8m/sec/sec)=9.0875939576336488274378098602812m/sec/sec

Did i get it right? I really don't think I did.

You are right.
It comes from the formula: g=G.M/R^2.
 
Thanks
 
Shouldnt the answer be in g's? Thats what really throughs me off.
