⚡ Quick Summary
This book assumes you have a good handle on high school math (algebra, trigonometry, and coordinate geometry) and are taking a calculus course at the same time. Don't worry if you haven't studied physics before – we'll start from scratch!
N/A
- Requires knowledge of algebra, trigonometry, and coordinate geometry (high school level).
- Assumes concurrent enrollment in a first calculus course.
- Calculus is discussed in Chapter 2.
- Starts each topic from zero level physics knowledge.

Conventions
Introductory College Level
⚡ Quick Summary
This book uses standard physics language (symbols, names, SI units) to make things clear. We'll use prefixes like 'micro' and 'mega' to keep numbers easy to read, and we'll pay attention to the units of measurements!
N/A
- Uses popular symbols, names, etc.
- Uses SI units consistently.
- Uses SI prefixes (micro, milli, mega, etc.).
- Uses coordinate sign convention in geometrical optics.
- Emphasizes dimensions of physical quantities.
- Includes units in equations for dimensional consistency.
Universal Constants and Astronomical Constants
11-12
⚡ Quick Summary
This section provides a list of important physical and astronomical constants, their values, units, and uncertainties. These constants are fundamental to many calculations in physics and astronomy.
['µ_0 = 4π × 10⁻⁷ N A⁻²', '∈_0 = 1 / (µ_0 * c²) C² N⁻¹ m⁻² = F m⁻¹']
This appendix presents a compilation of universal constants and astronomical constants commonly used in physics. Each constant is listed with its symbol, value, unit, and uncertainty (where applicable). The values are based on the 1986 revisions. The constants listed include: Constant of Gravitation (G), Speed of Light in Vacuum (c), Avogadro Constant (N_A), Gas Constant (R), Boltzmann Constant (k), Stefan-Boltzmann Constant (σ), Wien's Displacement Law Constant (b), Charge of Proton (e), Mass of Electron (m_e), Mass of Proton (m_p), Mass of Neutron (m_n), Permeability of Vacuum (µ_0), Permittivity of Vacuum (∈_0), Faraday Constant (F), Planck Constant (h), Rydberg Constant (R), Ground State Energy of Hydrogen Atom, and Bohr Radius (a_0). Additionally, astronomical constants such as Mass of the Sun, Radius of the Sun, Mass of the Earth, Mean Radius of the Earth, Mass of the Moon, Radius of the Moon, Mean Earth-Sun Distance, Mean Earth-Moon Distance, Escape Speed from the Earth, and Escape Speed from the Moon are provided.
