What is Meant By Parallel Vector?

Answer: Vectors that go in the same direction or the exact opposite direction are called parallel vectors. That is, any vector a, a, and it’s opposite, -a, are always vectors that are parallel to a. Taking this a step further, we can say that any scalar multiple of an is similar to a. So, a vector a and a scalar “k” are always parallel vectors (actual number).

When the angle between two vectors is 0 degrees, we say they are parallel. Parallel vectors are also known as collinear vectors. That is, two vectors that are parallel will always be similar to the same line, but they can go in the same direction or the opposite direction.
