Physical quantities are also classified into two types one is Scalar and the other is Vector quantity. To measure the physical quantities we need to introduce standards and units. Physical Quantities and Measurement Measurement of Volume and Density. Three fundamental units are Meter, Kilogram and Second. One kg is defined as the mass of a particular solid cylinder of platinum-iridium alloy kept at Sevres. That’s why we introduced the Physical quantity and unit. Selina Publishers Concise Physics for Class 6 ICSE Solutions all questions are solved and explained by expert teachers as per ICSE board guidelines.
