In the natural sciences, a vector quantity (also known as a vector physical quantity, physical vector, or simply vector) is a vector-valued physical quantity. [9] [10] It is typically formulated as the product of a unit of measurement and a vector numerical value , often a Euclidean vector with magnitude and direction.
[5] [6] [4] A simpler example of a bound vector is the translation vector from an initial point to an end point; in this case, the bound vector is an ordered pair of points in the same position space, with all coordinates having the same quantity dimension and unit (length an meters). [7] [8] A sliding vector is the combination of an ordinary ...

A physical quantity (or simply quantity) [1] [a] is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as a value , which is the algebraic multiplication of a numerical value and a unit of measurement .

Velocity is a physical vector quantity: both magnitude and direction are needed to define it. The scalar absolute value of velocity is called speed, being a coherent derived unit whose quantity is measured in the SI (metric system) as metres per second (m/s or m⋅s −1). For example, "5 metres per second" is a scalar, whereas "5 metres per ...
