Physics PRO Formulas-Problems

Stuck on physics homework or studying for a test? Physics: Formulas & Problems solves physics step by step: pick a topic, type your data in any unit, and the app rearranges the formula, converts everything to SI units and shows every step of the solution.

Made by a math and physics teacher for high school, AP Physics and college students.

★ 96 PHYSICS TOPICS WITH STEP-BY-STEP FORMULAS

• Choose what you want to find: the app solves the equation for that variable.

• See the formula while you enter your data.

• Automatic unit conversion (mph, °F, atm, cal, kΩ…).

• Each step explained, plus "What is it?", "When is it used?" and a final sentence that interprets the answer.

• Supporting images for every topic.

Topics included:

• Kinematics: uniform motion, constant acceleration, free fall, projectile motion, circular motion, pendulum.

• Dynamics: Newton's laws, friction, inclined plane, Atwood machine, gravitation, torque, collisions.

• Work, energy and power.

• Fluid statics: pressure, density, Pascal's and Archimedes' principles.

• Fluid dynamics: flow rate, continuity equation, Torricelli.

• Ideal gases: Boyle's, Charles's, Gay-Lussac's and the combined gas law.

• Thermodynamics: heat, calorimetry, thermal expansion, first law, Carnot.

• Waves and optics: Doppler effect, sound, Snell's law, lenses.

• Electricity and magnetism: Coulomb's law, electric field, Ohm's law, capacitors, Lorentz force, Faraday's law, transformers.

• Modern physics: photoelectric effect, E = mc², relativity, radioactive decay.
