Question

Satellites closer to the earth travel at lower speeds than satellites that are far away from earth.

(a) True

(b) False

This question was posed to me in a national level competition.

Asked question is from Satellite Orbits topic in chapter Satellite Communication of Avionics

Answer 1

Correct answer is (b) False

Easiest explanation: Satellites that are near earth have to move at higher speeds to sustain their orbit since the gravitational pull is much higher. Since the effect of gravity is less at higher altitudes, satellites that far away require less speeds.
