Parabola- a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side.
Ok, so basically a parabola is a geometrical shape that looks similar to a U and is mathematically represented in the picture by y=x². The St. Louis arch is an example of a parabola. Parabolas are also used to represent flight and motion. Any time something is thrown like a baseball or “Angry Bird” for example, the projectile`s flight path will resemble a parabola.
