Physics Handbook vs Introductory Physics Tutor

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 three 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. 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 — 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. SEVEN LANGUAGES English, Spanish, Arabic, French, Hindi, Thai and Russian — including the notation: subscripts are written the way your language writes them. Arabic reads right to left while formulas keep their standard direction. COMFORTABLE TO USE Light and dark themes, phones and tablets, portrait and landscape. No account, no ads, no in-app purchases. The reference text, translations and fonts are installed with the app, so every feature works offline. Your favourites, language and theme stay on your device. Written as a study aid and a quick reference, following standard school and introductory university treatments. Translations are written by hand, not machine-translated, and are still being refined — corrections are welcome at the support address.

Introductory Physics Tutor helps students build connected understanding across a complete Physics I and Physics II learning path. Rather than treating physics as a collection of formulas to memorize, the app moves through a Learn → Practice → Master cycle. Focused teaching, worked reasoning, visual questions, immediate coaching, interactive models, adaptive review, and exam preparation work together to help students understand what a problem is asking and why a solution works. WHAT’S INCLUDED • 19 physics topics spanning mechanics, energy, momentum, rotation, fluids, oscillations, waves, thermodynamics, electricity, magnetism, optics, quantum physics, and nuclear physics • 67 focused skills organized into a connected course roadmap • 624 practice and mastery questions • 273 visual-reasoning questions • Immediate choice-specific coaching and retry-until-correct learning • 17 interactive Explore labs • Adaptive review that identifies weak skills and directs you to what to study next • Physics I, Physics II, and cumulative exam review • 60-question timed full exam simulation • Progress and mastery tracking across the course LEARN WITH CONTEXT Each focused skill begins with concise teaching and worked reasoning before practice. The goal is not simply to recognize the right equation, but to connect diagrams, physical models, units, signs, and assumptions to the underlying physics. PRACTICE VISUALLY Many questions use force diagrams, motion relationships, energy models, circuits, fields, waves, thermodynamic processes, and other visual representations. Feedback explains why an answer works and helps rule out common misconceptions. EXPLORE THE PHYSICS Interactive labs let you change variables, make predictions, observe what happens, and connect the result back to the governing model. Explore vectors, projectile motion, free-body diagrams, energy, collisions, torque, fluids, oscillations, waves, thermal physics, electric fields, capacitance, circuits, magnetism, optics, photons, and nuclear decay. REVIEW WHAT MATTERS Adaptive Review turns missed ideas into focused relearning and fresh checks. Exam Review provides guided Physics I, Physics II, and cumulative practice, while the full simulation offers an independent timed test experience. TRY THE REAL TUTOR FREE Topic 1, Measurement & Vectors, is fully available so you can experience the complete Learn → Practice → Master approach, including visual reasoning, progress tracking, and the Vector Components Lab. A single Full Access purchase unlocks the remaining course, labs, adaptive review, and exam-preparation features. No subscription is required. Designed for iPhone and iPad, with layouts built to take advantage of both devices.
