Physics Formulas vs AP Biology Flashcards

PhysRef is the complete physics formula reference designed for students, engineers, and science enthusiasts. Access hundreds of formulas, physical constants, and built-in calculators - all without internet connection. COMPREHENSIVE FORMULA DATABASE Browse formulas organized by topic: Mechanics, Thermodynamics, Waves, Electricity and Magnetism, Optics, and Modern Physics. Each formula includes variable definitions, units, and related concepts. BUILT-IN CALCULATORS Stop doing manual calculations. Enter your known values and instantly compute the unknown variable. Every calculator validates inputs and displays results with appropriate units. PHYSICAL CONSTANTS TABLE Quick access to fundamental constants including speed of light, gravitational constant, Planck's constant, electron mass, Boltzmann constant, and dozens more. All values use standard reference data. UNIT CONVERTER Convert between units across 14 categories: length, mass, time, velocity, acceleration, force, energy, power, pressure, temperature, electric charge, electric current, angle, and frequency. PERSONAL NOTES Add your own notes to any formula. Perfect for exam prep, recording problem-solving strategies, or marking formulas you find tricky. FORMULA DERIVATIONS Understand where formulas come from. See step-by-step derivations that connect fundamental principles to the equations you use. WORKS COMPLETELY OFFLINE All content is bundled in the app. Study on airplanes, in basements, or anywhere without signal. No account required. No internet needed. DESIGNED FOR STUDENTS Covers content from AP Physics 1, AP Physics 2, AP Physics C, IB Physics, and introductory university physics courses.
