About this app
The essential physics reference for students and professionals. Browse 250+ formulas organized by topic, from mechanics to modern physics.
WHAT'S INCLUDED
Mechanics
Kinematics, dynamics, work and energy, momentum, rotational motion, gravitation, and oscillations.
Electricity and Magnetism
Electrostatics, circuits, magnetism, electromagnetic induction, and AC/DC analysis.
Thermodynamics
Heat transfer, laws of thermodynamics, kinetic theory, and entropy.
Waves and Optics
Wave properties, sound, reflection, refraction, lenses, mirrors, interference, and diffraction.
Modern Physics
Special relativity, quantum mechanics, atomic structure, and nuclear physics.
FEATURES
Formula Browser
Every formula includes a clear equation display, variable definitions with SI units, and a description of when to use it.
Built-in Calculators
Enter known values and solve for unknowns. Each calculator validates inputs and shows results with appropriate precision.
Physical Constants
Access fundamental constants including the speed of light, Planck's constant, gravitational constant, electron mass, and more. All values sourced from NIST.
Unit Converter
Convert between units across 14 categories: length, mass, time, velocity, acceleration, force, energy, power, pressure, temperature, electric charge, voltage, frequency, and angle.
Personal Notes
Add your own notes to any formula. Notes are saved locally and persist between sessions.
Formula Derivations
Understand where formulas come from with step-by-step derivations and explanations.
Related Formulas
Navigate between connected formulas. See which equations are derived from others and how they relate.
Search
Find formulas by name, variable symbol, or concept. Search history keeps track of your recent queries.
Bookmarks
Save frequently used formulas for quick access.
WHY PHYSREF
