Gravitational force is fundamentally about how mass curves spacetime, but Newton's law of universal gravitation gives us a practical formula: $F = G\frac{m_1 m_2}{r^2}$. The key insight is that this force depends on both masses and drops off sharply with distance—notice the inverse-square relationship. You just need to plug in the numbers carefully, keeping track of powers of 10, and let the math reveal how strongly Earth pulls on the satellite.
