i am in my 10th std i wanna know what are vectors?

Answer 1

vectors are "animals" that live in vector space. vector space is a set that fullfills certain requirements. every set that fullfills those requirements is called vector space (ie your vanilla coordinate plane is a vector space - points being elements, but so is a set of ie all polynomials up to a n-th degree) and it's elements are called vectors.

because the idea for vectors came from physics (ie when you push an object in a certain direction, then you can display that as an arrow in that direction, and length corresponds to the amount of force you're pushing it with), you usually display vectors as arrows which have direction and length.

Answer 2

Vectors are elements with magnitude and direction; an arrow Parts of a vector Tip- end of the arrow Tail - beginning of the arrow Types of vectors Fixed -A vector which is fixed in one location and cannot be moved Sliding -A vector which can move anywhere along its line of action Free -A vector which can move anywhere provided it keeps its proper angle or orientation Equal -Vectors are considered equal if they have the same magnitude and the same direction Negative -Two vectors are negative of each.

Answer 3

sure,
1> first u have to understand what is xy_plane.
2> then concept of co-ordinate geometry.
3> some trigonometric concepts.
now,
the vector is a representation for the direction oriented forces which are having some magnitudes also.

Answer 4

Any physical quantity which varies with the change of its magnitude as well as direction or both is said to be a vector quantity. Scalar quantity varies only with its magnitude.

Answer 5

the physical quantities which have magnitude as well as direction.
for example:
distance [s] is a scalar quantity. It is expressed as
5 km

displacement is a vector quantity.It is expressed as
5 km due east[direction]

Answer 6

vectors are lines having both magnitude and directions

Answer 7

vector (single dimensioned array) is a stream of homogeneous data elements

Answer 8

Positions or forces expressed of direction and magnitude.

Answer 9

certain quantities hav both magnitude & direction e.g-displacement(the shortest straight line distance between 2 points in a given direction),acceleration,velocity(velocity not speed)....n better still ask ur teacher!!!!

Answer 10

vectors are lines
