Master Physics Fundamentals Through Interactive Learning

Physics fundamentals are the core principles — Newton's laws, conservation of energy and momentum, waves, thermodynamics and electromagnetism — that every other topic in physics is built on. Master these and the rest of physics becomes far easier to follow.

Yes. Every article, calculator and interactive game on Physics Fundamentals is free to use, with no account required. We believe high-quality physics education should be available to everyone.

Articles are written and reviewed by a team of physics educators and graduate-level specialists across mechanics, thermodynamics, electromagnetism and modern physics, so explanations are both accurate and genuinely clear.

We cover the full introductory physics syllabus: kinematics, dynamics, energy, momentum, rotational motion, gravitation, oscillations, waves, optics, thermodynamics, electromagnetism and an introduction to modern physics.

Textbooks tell; we let you play. Alongside clear writing you get interactive simulations and calculators that let you change variables and watch the physics respond — building intuition a static page never can.

Start with kinematics and Newton's laws, use the matching game or calculator to test each idea, then work outward into energy, waves and electromagnetism. Each article links to the tools and topics that come next.
