What is parabola science?
parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. The vertex of the parabola is the point on the curve that is closest to the directrix; it is equidistant from the directrix and the focus.
What is a parabola in physics?
We define a parabola as the locus of a point that moves such that its distance from a fixed straight line called the directrix is equal to its distance from a fixed point called the focus. Unlike the ellipse, a parabola has only one focus and one directrix. The vertex of the parabola is at the origin.
What is a parabola Class 10?
A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point, which is the focus, and from a fixed straight line, which is known as the directrix. The set of all points in a plane that are equidistant from a fixed line and a fixed point in the plane is a parabola.
What does Directrix mean in math?
A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola, and the line is called the directrix . The directrix is perpendicular to the axis of symmetry of a parabola and does not touch the parabola.
What is a parabola short answer?
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped. It fits several superficially different mathematical descriptions, which can all be proved to define exactly the same curves. One description of a parabola involves a point (the focus) and a line (the directrix).
Why are parabolas so important in everyday life?
The parabola has many important applications, from the design of automobile headlight reflectors to calculating the paths of ballistic missiles. They are frequently used in areas such as engineering and physics, and often appear in nature.
What is parabola definition and example?
The definition of a parabola is a symmetrical plane curve that forms when a cone intersects with a plane parallel to its side. A u-shaped graph of a quadratic function is an example of a parabola. noun.
