Question #48129

what is physical quantities ?

Expert's answer

Solution:

A physical quantity is a physical property that can be quantified by measurement.

Examples:

If the temperature T of a body is quantified (measured) as 300 degrees Kelvin this is written, where T is the symbol of the physical quantity (NB degrees Celsius cannot be treated in this way)

If a person weighs 120 pounds, then "120" is the numerical value and "pound" is the unit. This physical quantity mass would be written as "120 lbs"
