When the starting point of these two parallel vectors is placed at the same point, their end point and common starting point should be in a straight line. Therefore the two vectors are parallel, also known as the two vectors are collinear".
As discussed in this passage, if two vectors are collinear, then they must be parallel vectors, so the proposition is false.
If you have to get to the bottom of it, then the correct way to say this proposition would be "if two vectors are parallel, but they are not necessarily collinear", because for example, a zero vector is parallel to an arbitrary vector, but you can't say which vector it is collinear with.
-
The two concepts are the same. In other words, parallel vectors are collinear vectors; Collinear vectors are parallel vectors.
This is due to the nature of vectors. Because we all know that vectors can be translated in any way. The translated vector is the same as the original vector!
It hasn't changed, this is the characteristic of vectors, so the two concepts you mentioned are actually the same, but the high school textbook introduces these two concepts, which actually doesn't mean anything special.

The online statement that "a collinear vector is not necessarily a parallel vector, but a parallel vector must be a collinear vector" is not true!
Vectors can move freely in parallel, so parallel and collinear are the same thing!
-
Yes. Collinear and parallel are the same concept.
Unless it's a zero vector. Zero vectors are also parallel.
-
For vectors, parallel and collinear are the same thing.
In the study of analytic geometry problems, such as two straight lines, there is a difference between parallel and colinear.

Parallel vectorsThe concept is:Collinear vectors, which refers to non-zero vectors in the same or opposite direction. The zero vector is parallel to the arbitrary vector.
Vectors: Quantities that have both magnitude and direction are called vectors.
Unit vector. A vector of length of 1 unit length.
Parallel vectors: Also called collinear vectors, non-zero vectors in the same or opposite direction.
Equality vector: A vector of equal length and in the same direction.
Opposite vector: A vector of equal length and in opposite directions.

Collinear vector relationship with chain-mining parallel vector.
Since any set of parallel vectors can be moved to the same straight line, parallel vectors are also called collinear shed excitation vectors.
The relationship between parallel vectors and equal vectors.
Vectors that are equal are necessarily parallel, but vectors that are parallel are not necessarily equal. Just because two vectors are equal doesn't necessarily have to coincide. Just use the two vectors that are of equal length and in the same direction. "Same direction" implies the parallel of vectors.

Vectors are collinear, that is, vectors are parallel. Vector collinear and vector parallelism can be treated as the same without distinction.
Because the vectors mentioned in high school textbooks are all free vectors, that is to say, the starting point of the vector can be moved arbitrarily, that is, the vector is still regarded as the same vector after translation. So two vectors are collinear, they can be considered parallel, and conversely, two vectors are parallel, they can also be considered to be collinear, and the conditions can be used interchangeably.
If the vector is expressed in the form (x,y), such as (2,5) affirmative and (2,5) two vectors are collinear; The vector (4,10) is parallel to the vector (2,5).
Collinear parallel theorem: If vector a is not equal to 0, the sufficient and necessary condition for vector b vector a is that there is a unique real number k, so that vector b = k (vector a).
If the vector a=(a1,a2), the vector b=(b1,b2), the vector b=k(vector a), i.e. (b1,b2)=k(a1,a2), (b1,b2)=(ka1,ka2), there is b1=ka1, b2=ka2
Because a1, a2, b1, and b2 are all to be quantified, they contain two layers of meaning that they are equal or proportional respectively, generally, k=1, vector a vector b is the same vector, that is, collinear; k is not equal to 1, vector a vector b (represented by numbers is not the same), that is parallel.

Vector collinear and vector parallel are the same.
Two vectors are collinear, meaning that two vectors are parallel. In short, a collinear vector is a parallel vector, and a non-zero vector with the same or opposite direction is called a parallel vector, which is denoted as a b, and any group of parallel vectors can be moved to the same straight line, so it is called a collinear vector.

The differences between parallel vectors and collinear vectors are described as follows:
There is no difference. Since any set of parallel vectors can be moved to the same straight line, parallel vectors are also called collinear vectors. Refers to non-zero vectors that are in the same or opposite direction.
The zero vector is parallel to the arbitrary vector. Vectors that are equal are necessarily parallel, but vectors that are parallel are not necessarily equal.
Introduction to Parallel Vectors:
Parallel vectors, also known as collinear vectors, refer to non-zero vectors that are in the same or opposite direction. where the zero vector is parallel to any vector. Its linear operations mainly include addition operations, subtraction operations, and multiplication operations.
Vectors that are equal are necessarily parallel, but vectors that are parallel are not necessarily equal. Just because two vectors are equal doesn't necessarily have to coincide. Just use the two vectors that are of equal length and in the same direction.
Among them, "the same direction is prepared to be rude" contains the meaning of vector parallelism.
Vector introduction: <>
Vectors are a fundamental concept in several natural sciences, including mathematics, physics, and engineering sciences. Refers to a tremor geometric object that has both size and direction and satisfies the parallelogram rule. Notation of vectors:
Typography is written as a letter in bold and written with a small arrow at the top of the letter" "If you give the beginning (a) and end (b) of the directional quantity, you can write the vector as ab. In a spatial Cartesian coordinate system, vectors can also be represented as pairs, e.g. (2,3) in the oxy plane is a vector.
Specific introduction: The concept of geometric vectors is abstracted in algebra to obtain a more general concept of vectors. Vectors are defined as elements of a vector space, and it is important to note that these abstract vectors are not necessarily represented by pairs, nor do the concepts of size and direction apply.
Therefore, when reading on a daily basis, it is necessary to distinguish what is said in the text according to the context"Vectors"What kind of concept is it?

1. The concept of parallel vectors: non-zero vectors that are the same or opposite to the square are called parallel rows.
2. Because any parallel vector can be moved to the same straight line, the parallel vector is also called a collinear vector. So the parallel vector must be a collinear stupid source vector, and the collinear vector must be a parallel vector, so the two concepts are the same.

<>1. The concept of parallel vectors: non-zero vectors with the same or opposite direction are called parallel rows.
2. The tremor cavity can be moved to the same line because of filial piety, so the parallel vector is also called the collinear vector. So the parallel vector must be a common line vector, and the collinear vector must be a parallel vector, so the concept of the two is the same.

Be. In mathematics, collinear vectors and parallel vectors are equivalent and are two names for the same thing. Because vectors in mathematics are vectors that can be translated.
Therefore, as long as it is a parallel vector, it must be translated so that it is in a straight line, that is, it must be a collinear vector. As long as it is a collinear vector, it must be translated so that it is in two parallel straight lines, that is, it must be a parallel vector.
Collinear vector vs. parallel vector relationshipSince any set of parallel vectors can be moved to the same straight line, parallel vectors are also called collinear vectors.
The relationship between parallel vectors and equal vectors. Vectors that are equal are necessarily parallel, but vectors that are parallel are not necessarily equal. Just because two vectors are equal doesn't necessarily have to coincide. Just use the two vectors that are of equal length and in the same direction.
"Same direction" implies the parallel of vectors.
