Can anyone explain briefly, What is a Collinear Vector?
The word collinear is formed by combining two words – co and linear. The word “co” here refers to “same” and “linear” means “in a line”. It means collinear literally means something which remains in the same line.
If two vectors lie along the same line, then they are known as collinear vectors. In mathematical language, any two parallel vectors are also called collinear vectors, since they point in either exactly same or exactly opposite direction. Thus, two vectors are said to be collinear if and only if they are either along same line or are parallel to each other.
