parabola (n.)

“a curve commonly defined as **the intersection of a cone with a plane parallel with its side**,” 1570s, from Modern Latin parabola, from Greek parabole “a comparison, parable,” literally “a throwing beside,” hence “a juxtaposition” (see parable), so called by Apollonius of Perga c.

## What is parabolic shape mean?

A parabola is a curve that looks like the one shown above. Its open end can point up, down, left or right. A curve of this shape is called ‘parabolic’, meaning ‘**like a parabola**‘.

## What is example of parabolic?

**The shimmering, stretched arc of a rocket launch** gives perhaps the most striking example of a parabola. When a rocket, or other ballistic object, is launched, it follows a parabolic path, or trajectory. This parabolic trajectory has been used in spaceflight for decades.

### What is parabola in real life?

**When liquid is rotated**, the forces of gravity result in the liquid forming a parabola-like shape. The most common example is when you stir up orange juice in a glass by rotating it round its axis. … The Bellagio’s fountains in Las Vegas, exhibit water in the shape of parabolas.

### Where do we use parabola in real life?

Parabolas are frequently used in physics and engineering for things such as the design of **automobile headlight reflectors** and the paths of ballistic missiles. Parabolas are frequently encountered as graphs of quadratic functions, including the very common equation y=x2 y = x 2 .

### What is a parabola in your own words?

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 the shape of ellipse?

An ellipse is **a circle that has been stretched in one direction**, to give it the shape of an oval.

### What is a Directrix and focus?

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 the meaning of parabolic path?

Parabolic path is defined as **the angle of trajectory of a projectile**.

### Where did the term parabola come from?

The word parabola is **derived from the Greek word parabole**, which means application or comparison. Italian astronomer and physicist Galileo Galilei (1564ā1642) worked out parabolic trajectories of projectiles in the early part of the seventeenth century.

### Why did they use parabola in microphones?

Parabolic Microphone Article Overview

Parabolic microphones are a type of microphone used **when sounds are too weak for normal microphones**, when a highly directional microphone is needed, or to boost sounds so they can be clearly heard by the human ear.

### What is the value of parabolic?

If the parabola opens up, the vertex represents the **lowest point** on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph.

### What is called ellipse?

In mathematics, an ellipse is **a plane curve surrounding two focal points**, such that for all points on the curve, the sum of the two distances to the focal points is a constant. As such, it generalizes a circle, which is the special type of ellipse in which the two focal points are the same.

### Is ellipse a circle?

A circle is a closed curved shape that is flat. … Ellipses vary in shape from very broad and flat to almost circular, depending on how far away the foci are from each other. If the two foci **are on the same spot**, the ellipse is a circle.

### WHAT IS A in ellipse?

What is the Equation of Ellipse? The equation of the ellipse is x**2a2+y2b2**=1 x 2 a 2 + y 2 b 2 = 1 . Here a is called the semi-major axis and b is the semi-minor axis. For this equation, the origin is the center of the ellipse and the x-axis is the transverse axis, and the y-axis is the conjugate axis.

### What does a parabola look like?

All parabolas are **vaguely āUā shaped** and they will have a highest or lowest point that is called the vertex. Parabolas may open up or down and may or may not have x -intercepts and they will always have a single y -intercept. … The dashed line with each of these parabolas is called the axis of symmetry.

### What is a parabolic relationship?

Definition. A parabola is **a curve where any point is at an equal distance from**: a fixed point (the focus ), and. a fixed straight line (the directrix )

### 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.

### Is the Eiffel Tower a parabola?

The Eiffel Tower “The Eiffel Tower”- **The bottom of the Eiffel Tower is a parabola** and it can be interpreted as a negative parabola because it opens down. The tower was named after its designer and engineer, Gustave Eiffel, and over 5.5 million people visit the tower every year.
