Measurement is the process of assigning numbers to a given physical quantity.

1.1 Physical Quantity

In describing the behavior of objects around us we have to consider to matter, space and time. A moving body covers distance with time and for an object to move energy is required. For the motion to take place, force must be applied. When an object is in the course of motion changes its speed within a given time interval we said that it is undergoing acceleration. In all this we have physical quantities which are measurable and whose values can be used in the mathematical expressions to give numerical description about the object in a question. The physical quantities are divided into two categories which are fundamental / basic quantities and derived quantities.
