This chapter mostly requires practicing and memorizing of formulas and units. Each physical quantity either fundamental or derived has a measuring unit The quantity without its unit is meaningless There is a number of systems to specify the measuring units of the fundamental physical quantities These systems include the French system The British system and The Metric system which is modified to the International. Multiplessub multiples of units.
Work Power and Energy. In Physics we can see that there are variables which are repeated for example r or R is used for radius and it is common in most of the formulas as well. Questions asked from this chapter are mostly related to finding dimensions conversions and find errors in measurement.
