Explanation:
Types of Vectors
Zero Vector
We know that all vectors have initial and terminal points. A Zero vector or a null vector is one in which these two points coincide. It is denoted as
0
. Since the magnitude is zero, we cannot assign a direction to these vectors. Alternatively, zero vectors can have any direction. Some examples of zero vectors are
AA
,
BB
, etc.
Unit Vector
A Unit vector is a vector having a magnitude of unity or 1 unit. A unit vector in the direction of a given vector
a
is denoted as
a
^
.
Coinitial Vectors
Coinitial vectors are two or more vectors which have the same initial point. For example,
AB
and
AC
are coinitial vectors since they have the same initial point ‘A’.
Collinear Vectors
Collinear vectors are two or more vectors which are parallel to the same line irrespective of their magnitudes and direction.
Equal Vectors
If two vectors
a
and
b
have the same magnitude and direction regardless of the positions of their initial points, then they are Equal vectors. These vectors are written as
a
=
b
.
Negative of a Vector
Let’s say that there is a vector
AB
having a certain magnitude and direction. Now, if there is a vector whose magnitude is same as that of vector
AB
but the direction is opposite, then it is called negative of the given vector
AB
. For example, vector
BA
is the negative of vector
AB
. It is written as
BA
= –
AB
.
Concept
Vector is a quantity that has both the magnitude and the direction
Explanation
A vector having it's initial point fixed is called as fixed vector.
Fixer vector is also known as position vectore
There are ten types of vectors such as Zero vectors , Unit vectors , Position Vector , Co-inital Vector , Like and unlike vectors , collinear Vector , Coplanar vector , Equal vector , displacement vector and negative of a vector.
Every type of vector has different definitions and
Here for position vector it's initial point is fixed
