Escape Velocity

“The first step toward truth is to let go of all that we know and hold dear.” —Arach Jalaal


Lowest velocity necessary for an object to escape the gravitational attraction of a particular planet or other object


  • The minimum speed needed for an object to “break free” from the gravitational attraction of a massive body
  • Earth’s Escape velocity is about 40,270 km/h (25,020 mph)
  • The speed at which the sum of an object’s kinetic energy and its gravitational potential energy is equal to zero
