How is the magnitude of a vector a scalar?

Answer 1

A vector magnitude is the number that is associated to the length of the vector.

Answer 2

The magnitude of a vector represents its size or length in a specific direction. It is a scalar quantity because it only has a numerical value and no associated direction. The magnitude is always positive or zero.

Answer 3

A vector has both magnitude and direction. If you separate magnitude from the directional component (or state it separately), the value for magnitude alone has to be scalar. As soon as you marry magnitude with direction, the combined values constitute a vector.

Answer 4

Scalars are fully described by a magnitude while a vector also includes a direction. Thus a vector without a direction is only a scalar. Ex: Vector: 10 miles west Scalar: 10 miles

Answer 5

Scalars are quantities that are described by a magnitude alone. A scalar quantity multiplied by a unit vector is not a scalar quantity but a vector quantity.
