The term ‘scalar quantity’ is defined as a quantity that has only one element of a number field, attached to a unit of measurements, such as degrees or meters. It is a quantity that exhibits magnitude or size only, i.e. it is defined by a numerical value, along with a measurement unit. For example, Speed of the car, body temperature, distance between two locations, etc.The rules of ordinary algebra can be applied for combining scalar quantities, such that scalars can be added, subtracted or multiplied, in the same way, as numbers. However, the operation of the scalar can only be possible, for the quantities with the same measurement unit.A mathematical quantity that needs two independent characteristics to describe it completely, i.e. magnitude and direction. Here magnitude represents the size of the quantity which is also its absolute value, while direction represents the side, i.e. east, west, north, south, etc. For example, Displacement between two points, velocity and acceleration of a moving body, force, weight, etc. A vector quantity follows the triangle law of addition. An arrow is used to indicate vector quantity, placed over or next to the symbol that denotes vector.
Multiplication of a Vector by a Scalar
A vector may be multiplied by a scalar by multiplying each of its components by that number. Notice that the vector does not change direction, only length. If A = (1,2) then 3A = (3,6).
