How does the altitude of an object influence the strength of atmospheric drag it experiences?
Answer
Lower orbits experience much stronger drag because atmospheric density is greater there
The concentration of air molecules is higher at lower altitudes; consequently, a satellite in a lower orbit experiences a much greater resistive force (drag) than one higher up.
