Escape Velocity

  • Velocity needed to escape from gravitational pull of an object
  • Escaping an orbit of an object

Formula

  • vescape=2Gmrv_{escape} = \sqrt{\frac{2Gm}{r}}
    • GG is the universal gravitational constant (see gravity)
    • mm is the mass of the object
    • rr is the distance to the object
