Physical Quantities: Anything measurable, like length, mass, time, velocity, force, etc..Units: Standard reference standards used to measure physical quantities (e.g., meter, second, kilogram).Fundamental/Base Units: Units for fundamental quantities (Mass [M], Length [L], Time [T], etc.).Derived Units: Units for derived quantities, expressed as combinations of base units (e.g., \(m/s\) for velocity).Dimensions: The powers to which fundamental quantities (M, L, T) are raised to express a physical quantity (e.g., Area = [L²], Density = [M¹L⁻³T⁰]).Dimensional Analysis: Using dimensions to check the consistency of physical equations (principle of homogeneity) and convert units.Measurement & Errors: Discusses accuracy, precision, and types of errors (systematic, random, gross) in measurements.
