Dimensional Analysis Quiz

Dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities and units of measurement, and tracking these dimensions as calculations or comparisons are performed.

Dimensional analysis is used to refer to the conversion of units from one dimensional unit to another, which can be used to evaluate scientific formulae.

Commensurable physical quantities are of the same kind and have the same dimension, and can be directly compared to each other, even if they are expressed in differing units of measurement.

<p>Incommensurable physical quantities are of different kinds and have different dimensions, and cannot be directly compared to each other, e.g. metres and grams, seconds and grams, metres and seconds.</p> Signup and view all the answers
