1. escape velocitynoun

   The minimum velocity at which an object must be moving in order for it to overcome the gravitational attraction of a massive celestial body, such as the earth or the sun, and escape beyond its gravitational field into free space. The velocity is calculated as though attained instantaneously at the surface of the celestial body, and is pointed directly away from its center, and neglecting effects of atmospheric friction. Rockets, which accelerate gradually and are moving rapidly at a high altitude when their fuel is exhausted or their engines shut off, may escape even if moving slightly slower at that point than the surface escape velocity. Compare orbital velocity.

1. Escape Velocity

   Escape Velocity is a song by The Chemical Brothers, released as a white label promotional single from their 2010 album Further. The version that appears on the single is different from that found on the album, in that it features no transition out of "Snow" or into "Another World." The song was broadcast in part on Pete Tong's radio show on BBC Radio 1. It was also played before its release in a Chemical Brothers DJ set at Coachella 2009, along with "Don't Think," which was ultimately released as a bonus track on the iTunes edition of Further. It was also used in the videogame Gran Turismo 5.

1. Escape velocity

   In physics, escape velocity is the speed at which the kinetic energy plus the gravitational potential energy of an object is zero. It is the speed needed to "break free" from the gravitational attraction of a massive body, without further propulsion. For a spherically symmetric body, the escape velocity at a given distance is calculated by the formula where G is the universal gravitational constant, M the mass of the planet, star or other body, and r the distance from the center of gravity. In this equation atmospheric friction is not taken into account. A rocket moving out of a gravity well does not actually need to attain escape velocity to do so, but could achieve the same result at any speed with a suitable mode of propulsion and sufficient fuel. Escape velocity only applies to ballistic trajectories. The term escape velocity is actually a misnomer, and it is often more accurately referred to as escape speed since the necessary speed is a scalar quantity which is independent of direction.
