分步代入计算过程

01Canonical Law: v_e = √((2 × G × M) / R)
02Given Inputs (Base Units): M = 5.9722e+24 kg, R = 6,371,000 m
03Solve for v_e (Escape Velocity): v_e = 11,186.17 m/s

Escape velocity v_e is the minimum ballistic speed required for a non-propelled object to escape the gravitational potential well of a primary body of mass M from radius R: v_e = √(2 × G × M / R).
