How to Find the Focus & Directrix of a Parabola in Vertex Form

WebThe directrix of this parabola is a horizontal line, the set of all points at a certain height in the parabola's plane. This height is the energy in the ball. In other words, the potential energy that the ball would have if it were at rest at that height equals the potential plus kinetic energy of the ball everywhere on its parabolic path. WebFocus and Directrix A parabola is a type of conic section, defined as follows: Given a specific point (the focus) and a specific line (the directrix), the parabola is the locus of all points such that its distance from the focus is equal to its perpendicular distance from the directrix, provided the focus doesn't lie on the directrix.
