1-1: Physical Quantities

Physics is one of the most important branches of the basic science, because it provides basic principles and fundamental laws and formulas for other science branches in order to be used in their work. This make physics very important for most subjects such as chemistry, medicine, engineering, astronomy, earth science and other sciences. It also makes the study and understanding of what is happening around us easy. The physical quantities measurement depends on the high precision and observations during the experimental work, while the student or the researcher is taking this measurement. This accurate measurement can be obtained by using the latest equipment.

Physical quantities are divided into two categories, which they known as basic quantities and derived quantities.
