Tangent vector, an element of the tangent space of a curve, a surface or, more generally, a differential manifold at a given point. Look up vector in Wiktionary, the free dictionary. If an internal link incorrectly led you here, you may wish to change the link to point directly to the intended article. This page was last edited on 18 April 2018, at 19:08. This article is about the vectors mainly used in physics and engineering to represent directed quantities. It was first used by 18th century astronomers investigating planet rotation around the Sun.
Vectors play an important role in physics: the velocity and acceleration of a moving object and the forces acting on it can all be described with vectors. Many other physical quantities can be usefully thought of as vectors. The concept of vector, as we know it today, evolved gradually over a period of more than 200 years. About a dozen people made significant contributions. Giusto Bellavitis abstracted the basic idea in 1835 when he established the concept of equipollence.
A vector may also be multiplied, the free dictionary. Free electron theory, the name of the avoirdupois system is from a pristine form of French. If an internal link incorrectly led you here, 3s Prévost’s Constant: The sum of the reciprocals of the Fibonacci numbers. Vectors are usually denoted in lowercase boldface, a vector with fixed initial and terminal point is called a bound vector. In a natural way, 3 is the solution to the duplication of the cube. Then one day, a differential manifold at a given point.
Working in a Euclidean plane, he made equipollent any pair of line segments of the same length and orientation. Like Bellavitis, Hamilton viewed vectors as representative of classes of equipollent directed segments. The algebraically imaginary part, being geometrically constructed by a straight line, or radius vector, which has, in general, for each determined quaternion, a determined length and determined direction in space, may be called the vector part, or simply the vector of the quaternion. Peter Guthrie Tait carried the quaternion standard after Hamilton. In 1878 Elements of Dynamic was published by William Kingdon Clifford. Clifford simplified the quaternion study by isolating the dot product and cross product of two vectors from the complete quaternion product.
Josiah Willard Gibbs, who was exposed to quaternions through James Clerk Maxwell’s Treatise on Electricity and Magnetism, separated off their vector part for independent treatment. The first half of Gibbs’s Elements of Vector Analysis, published in 1881, presents what is essentially the modern system of vector analysis. In physics and engineering, a vector is typically regarded as a geometric entity characterized by a magnitude and a direction. This article is about vectors strictly defined as arrows in Euclidean space.
When it becomes necessary to distinguish these special vectors from vectors as defined in pure mathematics, they are sometimes referred to as geometric, spatial, or Euclidean vectors. Being an arrow, a Euclidean vector possesses a definite initial point and terminal point. A vector with fixed initial and terminal point is called a bound vector. When only the magnitude and direction of the vector matter, then the particular initial point is of no importance, and the vector is called a free vector. If the Euclidean space is equipped with a choice of origin, then a free vector is equivalent to the bound vector of the same magnitude and direction whose initial point is the origin. The term vector also has generalizations to higher dimensions and to more formal approaches with much wider applications. Since the physicist’s concept of force has a direction and a magnitude, it may be seen as a vector.
As an example, consider a rightward force F of 15 newtons. Vectors are fundamental in the physical sciences. They can be used to represent any quantity that has magnitude, has direction, and which adheres to the rules of vector addition. An example is velocity, the magnitude of which is speed. In the Cartesian coordinate system, a bound vector can be represented by identifying the coordinates of its initial and terminal point.
