What is a parabola kid definition?
parabola. • a curve having every point an equal distance from. a fixed point (the focus) and a fixed line (the directrix).
What is a parabola simple definition?
1 : a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line : the intersection of a right circular cone with a plane parallel to an element of the cone. 2 : something bowl-shaped (such as an antenna or microphone reflector)
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.
What is a real life example of a parabola?
Everyday Parabolas Consider a fountain. The water shot into the air by the fountain falls back in a parabolic path. A ball thrown into the air also follows a parabolic path.
Where is the vertex located on a graph?
The vertex of a parabola is the point where the parabola crosses its axis of symmetry. If the coefficient of the x2 term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape.
What is a parabola a type of?
A parabola is a conic section. It is a slice of a right cone parallel to one side (a generating line) of the cone. You worked with parabolas in Algebra 1 when you graphed quadratic equations. We will now be investigating the conic form of the parabola equation to learn more about the parabola’s graph.
What is the importance of parabola in real 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 are some examples of parabolic shapes?
Real Life Parabola Examples Everyday Parabolas. Parabolas can, in fact, be seen everywhere, in nature as well as manmade items. Parabolas in Architecture and Engineering. Even architecture and engineering projects reveal the use of parabolas. Using Parabolic Reflectors to Focus Light. Parabolas in Spaceflight. Other Uses for Parabolas.
What determines a parabola’s shape?
In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U shaped. It fits several other superficially different mathematical descriptions , which can all be proved to define exactly the same curves. Part of a parabola (blue), with various features (other colours).

Why is suspension bridge a parabolic shape?
However, because the curve on a suspension bridge is not created by gravity alone (the forces of compression and tension are acting on it) it cannot be considered a catenary, but rather a parabola. The parabolic shape allows for the forces to be transferred to the towers , which upholds the weight of the traffic. For the suspension bridge in general the roadway is very nearly a uniformly distributed load, and each cable hangs down in a curve closely approaching that of a parabola.-
What is the shape of a parabola?
A parabola can be thought of as a one-sided ellipse. Where a typical ellipse is closed and has two points within the shape called foci, a parabola is elliptical in shape but one focus is in infinity .
