Define Following Term Coplanar Vectors

Define the following term : (a) Coplanar vectors (b) Modulus of a vector (c) Fixed vector (d) Unit vector

Answers:

(a) Coplanar vectors: The vectors which act in the same plane are called coplanar vector. 

(b) Modulus of a vector: The magnitude or length of a vector is called its modulus.

 (c) Fixed vector: The vector whose initial vector is fixed is called a fixed vector or localized vector. 

(d) Unit vector: A unit vector is a vector of unit magnitude drawn in the direction of a given vector.
