Question

Can be a vector scalar ?​

Answer 1

No, scalar and vector quantities are two different categories of a quantity.

So vector could not be considered to be scalar too.

But turning a vector to a scalar is possible. Only remove the direction of movement.

Answer 2

A scalar has only its magnitude, whereas a vector has a magnitude, a line where it lies, and a direction it points along that line.

The only way to associate vectors and scalars is to think of vector as of arrays of numbers. For example, this
`(2, 3, 5)` is a vector in
`\mathbb{R}^3`.

Under this logic, scalars are just vectors with dimension 1.
