A '''parabola''' is a curve on a plane, consisting of all the points that are equidistant from a point called the ''focus'' and a line, called the ''directrix''.
It is a conic section, the intersection of a plane and a cone where the plane is parallel one side of the cone.
The general [[algebra]]ic formula for a parabols is:
:<math>y = ax^2 + bx + c</math>
A parabola is the path taken by an object in motion subject to a uniform [[acceleration]], such as [[gravity]], ignoring friction.
