  • Escape velocity | Definition, Formula, Earth, Moon, Facts - Britannica
    Escape velocity, in astronomy and space exploration, the velocity needed for a body to escape from a gravitational centre of attraction without undergoing any further acceleration
  • What Is Escape Velocity? Physics Explained - ScienceInsights
    Escape velocity is the minimum speed an object needs to break free from a planet’s, moon’s, or star’s gravitational pull without any additional thrust For Earth, that speed is about 11 2 kilometers per second (roughly 40,000 km h or 25,000 mph)
  • Escape Velocity - Physics Book

  • Escape velocity - New World Encyclopedia
    For a given gravitational potential energy at a given position, the escape velocity is the minimum speed an object without propulsion needs to have sufficient energy to be able to "escape" from the gravity, that is, so that gravity will never manage to pull it back
