What is the dot product of parallel vectors

When there's a right angle between the two vectors, $\cos90 = 0$, the vectors are orthogonal, and the result of the dot product is 0. When the angle between two vectors is 0, $\cos0 = 1$, indicating that the vectors are in the same direction (codirectional or parallel).

A Dot Product Calculator is a tool that computes the dot product (also known as scalar product or inner product) of two vectors in Euclidean space. The dot product is a scalar value that represents the extent to which two vectors are aligned. It has numerous applications in geometry, physics, and engineering. To use the dot product calculator ...In mathematics, the dot product or scalar product [note 1] is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors ), and returns a single number. In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used.31. If they were parallel, you could write one direction as a scalar multiple of the other. Since you cannot do that as well as the cross-product is not zero, the vectors are not parallel. Mar 16, 2010. #3.The maximum value for the dot product occurs when the two vectors are parallel to one another (all 'force' from both vectors is in the same direction), but when the two vectors are perpendicular to one another, the value of the dot product is equal to 0 (one vector has zero force aligned in the direction of the other, and any value multiplied ...In mathematics, the dot product or scalar product [note 1] is an algebraic operation that takes two equal-length sequences of numbers (usually coordinate vectors ), and returns a single number.
