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 algebraic formula for a parabola is:
A parabola is the path taken by an object in motion subject to a uniform acceleration, such as gravity, ignoring friction.
