Question

Define the following term

(i) Equal vector

(ii) Unit vector

(iii) Co-initial vector

(iv) Negative vector​

Answer 1

Answer:

Equal Vectors

Two or more vectors are said to be equal when their magnitude is equal and also their direction is the same. The two vectors shown above, are equal vectors as they have both direction and magnitude equal.

Unit vector

A vector is a quantity which has both magnitudes, as well as direction. A vector which has a magnitude of 1 is a unit vector. It is also known as Direction Vector.

Co-initial vector

Co-initial Vectors: Any given two vectors are called as co-initial vectors if both the given vectors have the same initial point.

Negative vector

A negative vector is a vector which points in the direction opposite to the reference positive direction. A negative vector is a vector that has the opposite direction to the reference positive direction. Like scalars, vectors can also be added and subtracted.
