 Escape velocity is the minimum velocity a body must have in order to escape from the gravitational field of the earth.

 Escape velocity is the speed something has to go to break through Earth's gravitational pull.

 Escape velocity is sometimes misunderstood to be the speed a powered vehicle (such as a rocket) must travel to leave orbit, however this is not the case.
 Escape velocity is independent of the mass of the escaping object.

 Escape velocity is actually a speed (not a velocity) because it does not specify a direction.

 Escape velocity: The velocity required to escape from an object.
 It so happens that the relationship between the escape velocity and the circular orbit velocity is very simple.
 For the escape velocity this results in the square root of the sum of the squares of the escape velocities of all sources separately.
 The minimum effective escape velocity is reduced by the orbital velocity in a different way.
 Escape velocity as used here, the minimum velocity an object without propulsion needs to have to move away indefinitely from the earth.

 In Escape Velocity Nova, mankind has spread out into interstellar space, populating dozens of planets orbiting stars near and far from Earth and the Sun.
 Also, the distance from the center of the object r is in the bottom of the fraction, so the escape velocity DEcreases as the distance increases.

 At that time, the Newtonian theory of gravity and the concept of escape velocity were well known.
 We will discuss escape velocity using the concept of energy in the next book of the series, but it can also be gotten at using straightforward calculus.
(Web site)
 The term escape velocity is actually a misnomer, as the concept refers to a scalar speed which is independent of direction.
(Web site)
 The answer to this question can be found by combining Hubble's law with the formula for escape velocity.
(Web site)
 The simplest way of deriving the formula for escape velocity is to use conservation of energy.

 If a freefalling body at any position has the escape velocity for that position, this is the case for the whole orbit.
 For a body rotating about its axis the escape velocity with respect to the surface does depend on direction.
 A radial parabolic trajectory is a nonperiodic trajectory on a straight line where the relative velocity of the two objects is always the escape velocity.
 To simply state this, all objects on Earth have the same escape velocity.
(Web site)
 If an object is traveling as fast as or faster than escape velocity, then it will be able to leave Earth and fly off into space.
 This is "escape velocity", and is also the delta V required to land from deep space instead of landing from orbit.
 At velocities greater than the escape velocity, it becomes hyperbolic, and the object escapes into space.
(Web site)
 On the surface of the Earth the escape velocity is about 11.2 kilometres per second.
 This latter figure is totally feasible and within the range of the escape velocity for the surface of Earth.
 Escape velocity from the surface of the Moon is about onethird of this.
(Web site)
 Simply stated, it approximates the rocket burn out velocity minus the escape velocity at the range of burnout.

 Escape Velocity Learning Goal: To introduce you to the concept of escape velocity for a rocket.
(Web site)
 Escape velocity only applies to objects that have no propulsion or thrust.
(Web site)
 The criterion that separates the closed and open orbits is the escape velocity, which for the earth is 7 mi (11.3 km) per sec.
(Web site)
 Orbits and Satellites Although escape velocity is difficult and expensive to attain, it is fortunately not necessary to do so in many cases.
 But at the instant the propulsion stops, the vehicle can only escape if its speed is greater than or equal to the local escape velocity at that position.
(Web site)
 But at the instant the fuel runs out, the rocket can only escape if its speed is greater than or equal to the local escape velocity at that position.
(Web site)
 Hyperbolic and parabolic orbits are "escape orbits", achieved only when a body (or a spacecraft) exceeds the escape velocity of the Solar System.
 Radial hyperbolic orbit: An open hyperbolic orbit where the object is moving at greater than the escape velocity.
 After 2 revolutions in earth orbit, Apollo 8 's 3rdstage was fired to attain escape velocity and insert spacecraft on lunar trajectory.
(Web site)
 If a spacecraft is launched at a speed that is not quite high enough to allow the craft to reach escape velocity, the craft may go into orbit.
 The second, Pioneer 4, had the distinction of being the first U.S. spacecraft to reach “escape velocity,” i.e., speed sufficient to leave Earth orbit.
 When a ship attains escape velocity and leaves Earth, this is not the end of the force of gravitation on that ship.
 This may or may not be escape velocity, the speed at which your satellite will fly off into outer space and force you to start over with a new satellite.
 The escape velocity at a given height is times the speed in a circular orbit at the same height (compare this with equation (14) in circular motion).
(Web site)
 In more technical terms, escape velocity is a scalar and not a vector.
 Terms: Orbital velocity, escape velocity, synchronous orbit.
(Web site)
 The escape velocity at a given height is √2 times the speed in a circular orbit at the same height, compare (14) in circular motion.
 Part F Find the escape velocity for an object of mass that is initially at a distance from the center of a planet of mass.
(Web site)
 Since the mass M is on top of the fraction, the escape velocity increases as the mass increases.
(Web site)
 To calculate the escape velocity in Newtonian mechanics, consider a heavy object of mass M centered at the origin.
 In this problem, you will analyze the motion of an object of mass m whose initial velocity is exactly equal to escape velocity.
(Web site)
 In this case, r is the distance of the satellite from the primary focus, and v er is the escape velocity from the point r.
 Black holes give us a clue to this; if the escape velocity of a black hole is the speed of light then everything will be drawn in at light speed.
 So it is damned near the speed of escape velocity to NEVER EVERr return if it gets at the wrong side of Earth that gets a gravity assist.
 The escape velocity depends on your altitude; higher up there's less gravity, so escape velocity is lower.
 On the other hand, the escape velocity for Jupiter would be many times that of Earth's because Jupiter is so huge and has so much gravity.
 If the ball travels at the ESCAPE VELOCITY (see below), then the orbit will be OPEN and will be a parabola.
 At a certain even faster velocity (called the escape velocity) the motion changes from an elliptical orbit to a parabola.
