Etymology: Parabola \Pa*rab"o*la\, noun; plural Parabolas. [New Latin expression, from the Greek expression -- so called because its axis is parallel to the side of the cone. See Parable, and compare to Parabole.]. (Websters 1913) |

Aerospace | An open curve all points of which are equidistant from a fixed point, called the focus , and a straight line. See conic section.The limiting case occurs when the point is on the line, in which case the parabola becomes a straight line. (references) |

(From Wikipedia, the free Encyclopedia)
A parabola is a conic section generated by the intersection of a cone, and a plane tangent to either the cone or some plane tangent to the cone. If the plane is itself tagent to the cone, one would obtain a degenerate parabola, a line. In other words, a parabola is the locus of points which are equa-distant from a given point (the focus) and a given line (the directrix).
In Cartesian coordinates, a parabola with an axis parallel to the y axis with vertex (h, k), focus (h, k + p), and directrix y = k - p has the equation
A parabola has a single axis of reflective symmetry, which passes through its focus and is perpendicular to its directrix. The point of intersection of this axis and the parabola is called the vertex. A parabola spun about this axis in three dimensions traces out a shape known as a paraboloid of revolution. See also parabolic reflector.
A particle in motion under the influence of a uniform gravitational field (for instance, a baseball flying through the air, neglecting air friction) follows a parabolic trajectory.
