Quick Lesson on Parallel Vectors with Examples

Scalar reproduction causes parallel vectors. These are vectors that:

Have the very same or contrary direction and which are scalar multiples of each other.

In this subject, we will review the following important aspects of vectors:

How to Figure Out if Two Vectors are Identical.

About Parallel Vectors

Typically, two vectors are each other’s scalar multiples. Let’s suppose two vectors, an and also b, are defined as:

b = c * a.

Where c is some actual scalar number, in the above equation, the vector b is shared as a scalar multiple of vector a, and also the two vectors are claimed to be parallel. The indicator of scalar c will establish the instructions of vector b. If the worth of c is positive, c > 0, both vectors will undoubtedly have the same direction. If the value of c is adverse, c < 0, the vector b will certainly aim opposite the vector.

Similarly, from the above formula, the vector can express an as.

a = 1/c * b.

Hence, it is clear that they should be scalar multiples for any two vectors to be parallel.

Let’s consider the case when the value of c is absolute no. Then we can compose:.

b = 0 * a.

b = 0.

The vector b becomes a no vector in this situation, and the zero vector is thought about alongside every vector.

How to Establish if 2 Vectors are Identical.

To identify if two vectors are parallel or not, we inspect if the given vectors can be revealed as scalar multiples of each other. As an example, two vectors U and V, are parallel if there is an actual number, t, such that.

U = t * V.

This number, t, can be favorable, unfavorable, or zero.

In this area, we will talk about examples related to vectors and their step-by-step remedies. This will certainly help to construct a deeper understanding of parallel vectors.


An automobile is moving with a rate vector of V1 = 30 m/s North, and an additional car is relocating North with a velocity vector V2 = 60 m/s. Establish whether both velocity vectors are identical or not.


We have the adhering to information.

V1 = 30 m/s, North.

V2 = 60 m/s, North.

To figure out if the offered vectors are identical or not, we inspect if they can show as multiples of each other or contrarily. We can associate both vectors as.

V2 = 2 * (30 m/s).

V2 = 2 * V1.

V2 = 2 * (30 m/s).
