Question

What is meant by a parallel vector?

Answer 1

Parallel vector:

• The two vectors are in the same direction or exactly in the opposite direction.
• The vectors have the same angle but vary in magnitude.
• Vectors do not intersect each other.
• One vector is a scalar multiple of the other vector. Means $\overrightarrow{a}$ is one vector then the other vector is $\overrightarrow{b}=k\overrightarrow{a}$.
• The cross-product of any two parallel vectors is a zero vector.
