About Physical Quantities and Units
Physical quantities combine a numerical value with a unit, and are expressed using SI base units or derived units such as newtons, joules and pascals. The topic covers prefixes, unit conversion, dimensional analysis, significant figures and measurement uncertainty, while distinguishing scalar quantities from vectors where direction matters.
