Unit vector: -
Vector is a quantity which has magnitude as well as direction. Vectors can have the magnitude 1, 2, 3.
Unit vector is a vector which has the magnitude 1 or unit.
A line of given length and pointing towards a given direction, like an arrow, is the typical representation
A vector can be made Unit vector by dividing it by its length.
Any vector can be represented by providing its magnitude but a unit vector along its direction.
The process of adding vectors (two or more than two) is called 'addition or composition of vectors'.
When two or more than two unit vectors are added, we get a single vector called the resultant vector.
The resultant of two or more than two vectors is a single vector which produces the same effect as the individual vectors together produce.
Three laws have been evolved for the addition of vectors.
They are: -
1) Triangle law of vectors
2) Parallelogram law of vectors
3) Polygon law of vectors
