About

Physics Handbook

Features
Read full description

Physics Handbook is an offline reference for school and first-year university physics: 168 articles in 17 topics, each with its formula, the symbols explained, a worked example and โ€” in almost every case โ€” a calculator. EVERY TOPIC IN ONE PLACE Kinematics, dynamics, statics and hydrostatics, work and energy, momentum and collisions, rotation, oscillations, waves and sound, molecular physics and thermodynamics, electrostatics, direct current, magnetism and induction, electromagnetic oscillations and waves, optics, quantum and atomic physics, nuclear physics, special relativity. READ A FORMULA PROPERLY Each article opens with its main formula and 382 useful rearrangements in total, then a table of symbols with SI units, the conditions under which the formula holds, the physical meaning in three short paragraphs, and the mistakes that cost marks most often โ€” 505 of them collected across the book. SOLVE, NOT JUST LOOK UP 161 articles include a calculator. Pick the value you are looking for, type in what you know in the units shown, and the app solves the formula for that unknown. Angles are entered in degrees. LEARN FROM WORKED EXAMPLES All 168 articles contain a complete worked example: the given values, the reasoning step by step, and the answer with its unit. BUILD YOUR OWN CHEAT SHEET The cheat sheet screen lists formulas without the explanations, filtered by topic or by your starred articles โ€” a fast way to revise before a test. FIND IT FAST Search by the name of a law, a formula, a quantity or a symbol. Filter by topic, by favourites, or show only articles that have a calculator. THE TABLES YOU KEEP NEEDING 51 physical constants with values and units, 38 SI units with 11 prefixes, and a short guide to solving problems. TWENTY LANGUAGES English, Spanish, French, German, Italian, Portuguese (Brazil), Dutch, Swedish, Danish, Norwegian Bokmรฅl, Turkish, Vietnamese, Japanese, Korean, Chinese (Simplified and Traditional), Arabic, Hindi, Thai and Russian โ€” including the notation: subscripts are written the way your language writes them.
