● Physical quantities :: The quantities by which various physical phenomena occurring in nature can be understood, they are called physical quantities .
Such as - velocity , force , moment of inertia , etc.
In general physical quantities are two types
● Types of Vectors :: The types of vector are showing in below .
➤ Equal vector :: Two vectors are equal when both their magnitude and direction are equal.
➤ Parallel vector :: Two Vectors are parallel when theri direction are equal .
➤ Zero vector :: The vector the have zero magnitude and independent direction.
➤ Unit vector :: The ratio of a vector and its magnitude is called the unit vector of the vector.
➤ Negative vector :: Two Vectors they have same magnitude but opposite direction .
➤ Anti parallel vector :: Two Vectors the have opposite direction .
➤ Collinear vector :: Vectors with angle between 0 ° and 180 ° in others word they vector works along the same straight line .
➤ Coplanar Vectors :: when three Vector have in same plane .
➤ Orthogonal unit Vectors :: i^ , j^ and k^ are Orthogonal unit Vectors when the direction of X , Y and Z are equal to i^ , j^ and k^ .
➤ Polar vector :: Two vector their have same origin point .
For example - Displacement ,
➤ Axial vector :: The Vectors they represent rotation effect and follow left hand pech law's
● Vector Representation :: Vectors represents by arrow symbol and the Origin of vector called tail of vector and the final point of arrow called head of vector , in the side of head of vector we calculate direction.

Such as - velocity , force , moment of inertia , etc.
In general physical quantities are two types
- Scalar quantities
- Vector quantities
➤scalar quantities :: The physical quantities they have only magnitude are called scalar quantities.
Such as : - speed , pressure , energy , density etc.
➤Vector quantities :: The physical quantities they have both factor , direction and magnitude . In other way we can define , the physical quantity the have direction and magnitude simultaneously is called vector quantities.
Such as - Displacement , force , Current density etc.
There are some other physical quantities that are not completely defined by the magnitude and direction. Such physical quantities are called tensor quantities.

➤ Axial vector :: The Vectors they represent rotation effect and follow left hand pech law's
According to pech law , the direction of Vectors are always in rotation axis of VectorsFor example - Angular velocity , torque , Angular momentum .
● Vector Representation :: Vectors represents by arrow symbol and the Origin of vector called tail of vector and the final point of arrow called head of vector , in the side of head of vector we calculate direction.
