noun a symmetrical open plane curve formed by the intersection of a cone with a plane parallel to its side
In mathematics, a parabola is a curve where any point is at an equal distance from a fixed point (focus) and a fixed straight line (directrix). It is a conic section formed by the intersection of a cone and a plane parallel to one of the cone's sides.
In astronomy, parabolic orbits are a type of trajectory followed by comets and other celestial objects that are influenced by the gravitational pull of a central body. The shape of a parabola helps describe the path of these objects.
In architecture, parabolic arches and vaults are structural elements that provide strength and support to buildings. The geometric properties of a parabola allow for efficient distribution of weight and stress.
In engineering, parabolic reflectors are used in various applications such as satellite dishes, solar cookers, and reflective telescopes. The reflective properties of a parabola help focus incoming waves or light to a single point.
In physics, parabolas are often used to model the trajectory of objects in free fall under the influence of gravity. The shape of a parabola allows for accurate predictions of the path of a projectile.
In mathematics, a parabola is a curve where any point is at an equal distance from a fixed point (focus) and a fixed straight line (directrix). It is commonly used in algebra, calculus, and geometry.
Engineers may use parabolas in the design of structures such as bridges, arches, and satellite dishes to achieve optimal strength and stability.
Physicists often encounter parabolic motion in the study of projectile motion, optics, and gravitational fields. The shape of a parabola can describe the trajectory of a projectile under the influence of gravity.
Astronomers may use parabolic reflectors in telescopes and antennas to focus incoming light or radio waves. The reflective surface of a parabolic mirror can help gather and concentrate electromagnetic radiation.
