Question : Once a satellite has been launched into orbit, the only force governing its motion is the force of______________.
Option 1: friction
Option 2: elasticity
Option 3: gravity
Option 4: fuel driven
Correct Answer: gravity
Solution : The correct option is gravity.
Once a satellite has been launched into orbit, the only force governing its motion is the force of gravity. The gravitational force between the satellite and the celestial body it is orbiting (usually Earth) is what keeps the satellite in its orbital path. This force is responsible for the satellite's circular or elliptical motion around the celestial body. In the absence of other significant forces, such as atmospheric drag, the gravitational force is the dominant factor determining the satellite's orbital behaviour.
