Physics Zen vs Physics Handbook

Physics Zen turns physics into focused, repeatable practice. Work through fresh generated problems, check your answer instantly, and open the theory or worked solution exactly when you need it. A COMPLETE PHYSICS PATH Practice 66 skills across 21 topics: • Mechanics: motion, projectiles, forces and friction, accelerating and rotating frames, energy, momentum, centre of mass, rotation, circular motion, gravitation, oscillations and fluids • Electricity and Magnetism: electric fields, circuits and the Wheatstone bridge, capacitors, RC transients, magnetic fields and the Hall effect, induction, inductance and AC • Waves and Optics: wave graphs, sound, interference, reflection, refraction, lenses and diffraction • Thermodynamics: heat, gas laws, kinetic theory, entropy, engines and renewable energy • Modern Physics: photons, Compton scattering, black-body radiation, matter waves, X-rays, nuclear physics, particle physics and special relativity EXAM PREP Fifteen exam paths, each built from the topics its exam actually tests: • AP Physics 1, AP Physics 2 and AP Physics C: Mechanics, with free-response items that give follow-through marks • AP Physics C: Electricity and Magnetism, with calculus practice on Gauss's and Ampère's laws and RC, LR and LC circuits • NY Regents Physics, built on the Reference Tables • A-Level Physics, with required-practical data analysis: tables, gradients and uncertainties • HKDSE Physics (Hong Kong) • Abitur Physik, with fine-beam tube and Wien filter labs • FSP Physik (Studienkolleg), for the Feststellungsprüfung at a German Studienkolleg • French Bac physics, including Newton's law of cooling and the telescope; chemistry and the practical assessment are not included • Japan's University Entrance Common Test in Physics and Basic Physics, with digit-cell answers • Korea's CSAT (Suneung) Physics I, and the physics part of CSAT Integrated Science from 2028 • Taiwan's Advanced Subjects Test (分科測驗) Physics, which also covers the physics in the GSAT (學測) science paper • Board-specific gravity conventions Every item is original practice, not an official exam paper. BUILT FOR PRACTICE Generated Problems: Practise fresh parameter combinations across multiple difficulty levels. Mastery Progression: A five-level bucket system moves from foundations to multi-step problems as you demonstrate understanding. Theory Beside the Problem: Open concise explanations, formulas and worked examples without leaving your session. Mistake Journal: Wrong answers are saved automatically. Retry the same concept later with fresh numbers. Visual Physics: Graphs, force diagrams, circuits, waves, rays, energy levels and fluid scenes support the problems that need them. Offline First: The curriculum and generator work without an internet connection. Optional sign-in adds cross-device sync. Focused Interface: No ads, no coins and no lives. Includes light and dark themes. Content is available in thirteen languages: English, German, French, Spanish, Brazilian Portuguese, Dutch, Swedish, Norwegian, Japanese, Simplified Chinese, Traditional Chinese, Korean and Russian. HOW IT WORKS 1. Choose a section, topic or exam path. 2. Solve a generated problem at your current level. 3. Check your answer and read the worked solution. 4. Build mastery and return to mistakes that need another pass. Most skills are free, and Kinematics is free end to end. Premium unlocks the last skill of each topic, the exam-prep paths and detailed statistics. Subscription and lifetime options are shown in the app with local pricing before purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel them in your App Store account settings.

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 — in almost every case — 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 short paragraphs, and the mistakes that cost marks most often — 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. 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 — 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. 48 LANGUAGES Interface available in 48 languages. Arabic, Hebrew and Urdu read right to left while formulas keep their standard direction. COMFORTABLE TO USE Light and dark themes, phones and tablets, portrait and landscape. Physics Pro AI tutor: step-by-step physics explanations on your device Problem scanner: camera or photo, review the text before asking AI tutoring requires iOS/iPadOS 26 or later on a compatible device with Apple Intelligence enabled and its model ready. AI answers can contain mistakes. The tutor uses a language supported by Apple Intelligence, on-device Apple Translation where available, or English with a short note. The scanner and handbook work without AI. All formulas and calculators remain free. Monthly and yearly plans are auto-renewing subscriptions; manage or cancel them in App Store settings. Lifetime is a one-time purchase with no automatic renewal. Terms: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
