Topic 1
Units make measurements meaningful, and dimensions reveal how physical quantities are related.
Topic 2
No measurement is exact, so Physics uses error estimates and significant figures to express reliability.
Topic 3
A vector has both magnitude and direction, so operations on vectors must respect geometry as well as size.

Topic list
Topic 1
This topic builds the language of Physics through SI units, dimensional formulae, homogeneity, and the practical use and limits of dimensional analysis.
Topic 2
Measurement becomes trustworthy only when errors, precision, accuracy, least count, and significant figures are handled correctly.
Topic 3
Vector algebra gives Physics its direction-sensitive language through scalar quantities, vectors, resolution, and operations such as addition, dot product, and cross product.
