Document Summary
A space station revolves around the earth as a satellite, 100 km above earth s surface. The expression for the acceleration due to the gravity is expressed as follows: Here, g is the universal gravitational constant, is the mass of the earth, and r is the distance from center of the earth and the point where we want to find the g. The gravitational force on the astronaut on the earth surface is, In the above expression g and are constants. The value of the g will change with respect to the value of r. Consider a space station revolves in orbit 100 km above earth s surface. Find the g value at space station as follows: After substituting the all constant values (mass of earth, g), the value of the g is 9. 5. When comparing 100 km with r, it is negligible. The force on the astronaut in the space station is,
