One topic, as StudyPath teaches it.
This topic covers how physical quantities are measured and described: units and dimensions tell us what a quantity means, while scalars and vectors tell us how it behaves mathematically. It matters in mechanics because correct units prevent numerical errors, dimensional analysis helps check equations, and clear distinction between scalars and vectors is essential for solving motion and force problems.
