Question

why negative vector is not anti parallel vector...
it is given that both have opposite direction.
​

Answer 1

Explanation:

because they have same direction but different magnitude

Answer 2

HEYA!!

A negative vector for a given vector is a vector of same magnitude but acting in opposite direction.An antiparallel vector for a given vector is any vector acting in opposite direction.

A negative vector is an antiparallel vector, but an antiparallel vector is not necessarily a negative vector.
