Free Physics Formulas PDF: Key Equations & Worked Examples
What it is
- A concise, downloadable PDF that collects fundamental physics formulas across core topics and pairs many formulas with short worked examples.
Typical contents
- Mechanics: kinematics, Newton’s laws, energy, momentum, rotational motion (torque, angular momentum), simple harmonic motion.
- Waves & Optics: wave equation, speed/frequency/wavelength relations, interference, lenses/mirrors formulas.
- Electricity & Magnetism: Coulomb’s law, electric field/potential, Ohm’s law, circuits, magnetic force, Faraday’s law.
- Thermodynamics & Statistical: ideal gas law, first/second law statements in equation form, heat capacity relations.
- Modern Physics: photon energy, de Broglie wavelength, basic relativity formulas (time dilation, energy–mass equivalence).
- Constants & Conversions: common physical constants, unit conversions, vector operation reminders.
- Worked examples: 1–2 short, stepwise problems per major topic demonstrating formula choice, substitution, and unit checking.
- Quick reference pages: one- or two-page cheat sheets for exam revision.
Who it’s for
- High school and introductory college students, tutors, and anyone needing a compact reference.
How to use it effectively
- Keep the one-page cheat sheet for quick review.
- Study worked examples to learn problem-selection strategies.
- Memorize common constants and units shown.
- Practice by re-solving the examples without looking, then try related problems.
Where to get one
- Look for educational sites, university course pages, or reputable physics textbook companion sites that offer free PDFs or printable cheat sheets.
