- Appendix A: Vectors and vector arithmetic
- This page explores the differences between vectors and scalars, emphasizing that vectors have both magnitude and direction while scalars only have magnitude. It discusses the graphical representation of vectors, their components, and methods for finding their magnitude and direction. The page also covers vector addition, showcasing both graphical and algebraic techniques and highlighting commutative and associative properties.
- Appendix B: Units and unit conversions
- This page emphasizes the significance of units of measurement and precise definitions in conveying physical properties accurately, noting that different unit systems cannot be combined directly. It contrasts US customary units with the metric (SI) system, highlighting base and derived SI units, along with standardized prefixes.
- Appendix C: Answers to selected questions
- This page provides a comprehensive overview of key concepts in physics, including scientific theories and laws, motion—such as displacement and velocity, mechanical energy conservation, and calculations involving forces and energy transitions. It explores topics from electrical circuits and magnetism to nuclear physics, discussing decay processes, energy calculations with Einstein’s equation, and practical applications of these formulas.
