What is Gravitational Field Strength?
The gravitational field strength at any point can be defined as the force per unit mass placed at the point in the field.
Formula for Gravitational field strength:
 |
| Gravitational Field Strength |
What is Geostationary Orbit?
Geostationary orbit refers to a body orbiting a fixed position above the earth. For example a satellite moving with geostationary orbit around the earth has to have the same period of rotation as the earth (24hrs) therefore allowing it to remain above the same geographic area on the earth.
What is Escape Velocity?
Escape velocity refers to the minimum velocity a body needs to escape the gravitational pull of the earth.
Formula for escape velocity:
 |
| Escape velocity |
Where:
V is escape velocity
G is universal gravitational constant
me is mass of the earth
re is radius of the earth
2 Response to Gravitational Field Strength, Geostationary Orbit & Escape Velocity
It would have been great to be able to copy and paste those formulas! :) Thanks anyway for a nice post.
the formulas are saved as images and not text, all you have to do right click copy when over the image
