a plane curve formed by the intersection of a right circular cone with a plane parallel to a generator of the cone; the set of points in a plane that are equidistant from a fixed line and a fixed point in the same plane or in a parallel plane. Equation: y2 = 2px or x2 = 2py.

A parabola is a regular open plane curve which is formed by the intersection of a cone with a plane parallel to its side. The shape of this curve is normally followed by a projectile that is under the power of gravity.
