what is vector?

Answer 1

both magnitude &direction.

Answer 2

dear friend,

in mathematics, vector is a value that defines both "quantity" and "direction" of a particular object. (scalar is a value that defines only "quantity". e.g. "weight")
for example:-
1) a car moving in a particular direction, assume it is going to east and has moved 50 kms. so east is the "direction" and "50 kms" is the quantity.
This value can easily be shown by drawing a line (shows the approx. distance (quantity)) with an arrow showing the direction.

i would also like to tell you something about addition of vectors. it goes difficult if you do not understand this.
1) consider a triangle abc. each end having a arrow showing the direction. this three lines "ab", "bc" and "ac" represents vectors.
2) let "a" be a point say "delhi" you are in delhi now. you are going to calcutta "b" and then to bombay "c". (from a to b to c)
3) therefore the resultant vector "ac" gives you the value of minimum distance and actual distance you had taken to go from delhi to bombay.

see, this is what it is used for. now if you come back to delhi from bombay "ca", then the total distance travelled by you in the vector sense is "zero" because you are still there where you were before.
hope you understood it. unfortunately i could not explain you with the help of a drawing.

bye.

Answer 3

Vector may refer to:

Mathematics and Physics------
An element in a vector space
Vector (spatial), an object defined by both magnitude and direction
Probability vector

Philosophy------
Truth Vectors

Computer Science-----
A Dynamic array, a data structure, based on an array, which is able to grow or shrink as needed
Vector (STL), a data type in the Standard Template Library used in the C++ programming language
Vector processor, a computer processor which works on arrays of several numbers at once
Dope vector
Vector graphics, computer graphics defined by geometric primitives instead of pixels
Vector (computing), the method that malicious code (viruses, etc) uses to propagate itself

Biology----
A vector in biology has many several meanings:
An organism that transmits disease by conveying pathogens from one host to another
A virus used to deliver genetic material into a cell
A piece of DNA meant to carry DNA fragments into a host cell

Answer 4

Mathematics.
A quantity, such as velocity, completely specified by a magnitude and a direction.
A one-dimensional array.
An element of a vector space.
Pathology. An organism, such as a mosquito or tick, that carries disease-causing microorganisms from one host to another.
Genetics. A bacteriophage, plasmid, or other agent that transfers genetic material from one cell to another.
A force or influence.
A course or direction, as of an airplane.

Answer 5

A vector is a value defined by both a quantity and a direction, as opposed to a scalar, which only has a quantity.

Answer 6

Vector is synonymous with direction.

Answer 7

an object defined by both magnitude and direction

But am not totally sure of your questions orgin as there are lots of different areas as the word vector is used such as automotive, biology, computer programming, aeronautics, and the above mention of mathmatics.

Answer 8

its something which has the direction factor
like
velocity is vector and sped is scalar
calculation of velocity involves direction
but speed doesnt
ok bye

Answer 9

The direction you're heading to.
