What Are Physics Calculators?
Physics calculators apply validated scientific formulas to problems across the full spectrum of physics — from everyday Newtonian mechanics to quantum effects, thermodynamics, electromagnetism, optics, fluid dynamics, and astrophysics. This is one of the largest categories on the site, covering 472 tools.
What You Can Calculate
- Mechanics — calculate acceleration, velocity, force, momentum, torque, work, power, kinetic energy, potential energy, angular velocity, centripetal force, projectile motion, free fall, and simple harmonic motion.
- Electromagnetism — apply Ohm’s law, compute electric field, electric potential, capacitance, inductance, resistance, Coulomb’s law, Lorentz force, magnetic field, and RLC circuits.
- Thermodynamics — use Carnot efficiency, heat capacity, latent heat, thermal expansion, entropy, heat transfer coefficients, Stefan-Boltzmann law, and calorimetry.
- Fluid mechanics — apply Bernoulli’s equation, Reynolds number, Darcy-Weisbach, hydraulic pressure, buoyancy, flow rate, Stokes’ law, and viscosity.
- Optics — calculate focal length, lens equation, mirror equation, Snell’s law, diffraction grating, Brewster’s angle, depth of field, and telescope magnification.
- Quantum & atomic physics — use the Rydberg equation, de Broglie wavelength, photoelectric effect, Bohr model, Heisenberg uncertainty, electron configuration, and Compton scattering.
- Relativity & astrophysics — compute time dilation, length contraction, relativistic kinetic energy, Schwarzschild radius, escape velocity, orbital velocity, and Hubble’s law.
- Waves & sound — calculate wave speed, wavelength, frequency, Doppler effect, decibels, beat frequency, and resonant frequency.
