Formula and explanation
Relation: G(M m)/(r²) = m(v²)/(r) = mω² r = m(4π²)/(T²)r. Conditions: Central body mass M > > orbiting body mass m, and the orbit is approximately uniform circular motion. Explanation: This is the fundamental equation for analyzing celestial motion (e.g., satellite orbiting a planet).
