Parabolic trajectory — In astrodynamics or celestial mechanics a parabolic trajectory is a Kepler orbit with the eccentricity equal to 1. When moving away from the source it is called an escape orbit, otherwise a capture orbit.Under standard assumptions a body… … Wikipedia
Escape velocity — In physics, escape velocity is the speed where the kinetic energy of an object is equal to the magnitude of its gravitational potential energy, as calculated by the equation,:U g = frac{ Gm 1m 2}{r}.It is commonly described as the speed needed to … Wikipedia
Escape orbit — An escape orbit (also known as C 3 = 0 orbit) is a high energy parabolic orbit around the central body. A body in this orbit has at each position the escape velocity with respect to this central body, for this position. If this energy were… … Wikipedia
parabolic velocity — noun : the speed at which a body at any point in a central gravitational field must move in order that its orbit be a parabola and which when the gravitational field is due to a spherical mass (as the earth) is equal to the velocity of escape * * … Useful english dictionary
