Why do engineers design satellite need to understand gravity?

Engineers designing satellites must understand gravity because it plays a crucial role in determining the satellite's orbit and stability. Gravity affects the satellite's trajectory, velocity, and the forces acting upon it, influencing how it interacts with other celestial bodies. A thorough understanding of gravitational forces allows engineers to calculate the necessary parameters for launch, positioning, and maintaining the satellite's operational orbit effectively. Additionally, this knowledge helps in predicting satellite behavior over time, ensuring reliable functionality.
