About this app
Physics Formulas is a clear reference of physics formulas and equations for high school and first-year university: 264 formulas in 61 topics, explained with symbols, SI units, diagrams and worked examples.
From v = v₀ + at and ΣF = ma to V = IR and E₀ = mc², every physics equation is typeset cleanly, explained in plain language and works offline.
Every formula comes with a list of what each symbol means and its SI unit. The topic pages include worked examples with real numbers, practice questions with tap-to-reveal answers, and notes on common mistakes and sign conventions.
What you will learn
• Units and Constants: SI base and derived units, SI prefixes and unit conversion, vectors and components, and a table of physical constants with CODATA 2022 values from NIST
• Motion (Kinematics): motion in a straight line, the constant-acceleration equations, free fall and projectile motion
• Newton's Laws and Forces: Newton's laws of motion, weight, normal force, tension and springs, friction and inclined planes
• Work, Energy and Power: the work-energy theorem, potential energy, conservation of energy, power and efficiency
• Momentum and Collisions: momentum and impulse, elastic and inelastic collisions, center of mass
• Circular Motion and Gravitation: uniform circular motion, Newton's law of gravitation, orbits and escape speed
• Rotation: rotational kinematics, torque and equilibrium, moment of inertia, rotational energy and angular momentum
• Oscillations and Waves: simple harmonic motion, pendulums, wave basics, superposition and standing waves
• Sound: speed and intensity of sound, decibels, resonance in pipes, the Doppler effect and beats
• Fluids: density and pressure, buoyancy and Archimedes' principle, fluid flow and Bernoulli's equation
• Heat and Thermodynamics: temperature and thermal expansion, specific heat and phase changes, heat transfer, ideal gases and kinetic theory, the first and second laws of thermodynamics, heat engines
• Electrostatics: charge and Coulomb's law, electric field, electric potential, capacitors
• Electric Circuits: current, resistance and Ohm's law, resistors in series and parallel, EMF and Kirchhoff's rules, RC circuits, alternating current
• Magnetism and Induction: magnetic force, magnetic fields of currents, Faraday's law and Lenz's law, inductance and transformers
• Optics: reflection and refraction, plane and curved mirrors, thin lenses, interference and diffraction
• Modern Physics: photons and the photoelectric effect, matter waves and uncertainty, the Bohr atom and spectra, nuclei and binding energy, radioactive decay, special relativity
Features
