Physical QuantityAphysical quantityis aquantityinphysicsthat can be measured.Or a physical quantity is a physical property that can be quantified. Examples of physical quantities aremass,volume,length,time,temperature,electric current.Classification of the Physical Quantities This brief article describes the two types of physical quantities: scalars and vectors. The scalar quantities can be described completely by their magnitude, while for describing the vectors the magnitude as well as direction is required. Read on for more details.In the scientific and engineering studies a number of physical quantities have to be measured and there is close interrelationship between them. Many times a number of operations like addition, subtraction, multiplicati
