1.	Define :(i) Unit vector(ii) Free vector(iii) Co-initial vector(iv) Co-terminus vectors
Answer» (i) Unit vector: A unit vector is a vector of unit magnitude drawn in the direction of a given vector. (ii) Free vector: A vector whose initial point is not fixed is called a free vector or non-localised vector. (iii) Co-initial vector: The vectors which have the same initial point are called co-initial vectors. (iv) Co-terminus vectors: The vectors which have the common terminal point are called co-terminus vectors.

Answer»

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

(ii) Free vector: A vector whose initial point is not fixed is called a free vector or non-localised vector.

(iii) Co-initial vector: The vectors which have the same initial point are called co-initial vectors.

(iv) Co-terminus vectors: The vectors which have the common terminal point are called co-terminus vectors.
