Physics Calculators: 251 Free Tools

Solve physics problems faster with calculators for mechanics, electricity, thermodynamics, waves, fluids, optics, engineering, quantum physics, relativity, and astrophysics.

251 physics calculators

Physics formulas, calculations, and worked problem tools

CalcNovaHub's Physics collection brings together calculators for high-school physics, AP Physics, college courses, engineering fundamentals, and practical problem solving. Each calculator focuses on a specific relationship so you can enter known values, check units, calculate the result, and review the formula behind the answer.

If you're studying classical mechanics, start with the Acceleration Calculator, Newton's Second Law Calculator, Projectile Motion Calculator, and Work-Energy Theorem Calculator. For circuits and electromagnetism, useful starting points include Ohm's Law, Coulomb's Law, RC Time Constant, and RLC Q-Factor & Bandwidth.

The collection also covers thermal physics, fluid mechanics, optics, sound, quantum mechanics, nuclear physics, relativity, and astrophysics. Use the topic links below to jump directly to the subject you need, or search the full set of 251 calculators by formula, concept, or calculator name.

How to use the Physics calculator hub

Choose the calculator that matches the quantity you need to find, then confirm that the inputs correspond to the variables in the equation. Physics calculations are especially sensitive to units, sign conventions, reference frames, and assumptions, so convert values to compatible units before interpreting the result.

For students

Use the calculators to check homework steps rather than replacing them. Write the governing equation first, identify the known and unknown quantities, substitute values with units, and compare your manual result with the calculator. The expanded calculator pages include formula explanations, examples, common mistakes, and interpretation guidance to help you understand why the result makes sense.

For engineering and applied problems

Check the model assumptions before using a result in design work. Many introductory formulas assume ideal components, constant properties, small deformations, incompressible flow, negligible losses, or simplified geometry. When a calculator states an assumption or limitation, treat it as part of the calculation—not as optional background information.
