Most physics resources either oversimplify until they're useless or drown you in equations before you understand what's happening. We try to do neither.
We believe physics is one of the most beautiful and useful subjects ever discovered — and one of the worst taught. Students arrive at university having memorized equations they can't intuitively justify, then leave hating a subject they never really understood.
PhysicsFundamentalsInfo exists to change that. We write physics explanations the way a great tutor would explain them in person: starting with the physical intuition, then introducing the mathematics, then practicing with real problems until it clicks. Every article ends with worked problems because you cannot learn physics passively. You learn by doing.
Every topic opens with the real-world phenomenon — what's actually happening, why it matters, where you encounter it. Equations come after the picture is clear in your mind.
We don't just state formulas. Every article includes five to eight problems solved step-by-step, showing exactly how to apply what you've learned.
Our labs let you manipulate variables and watch the physics respond. Reading about projectile motion is one thing; launching a thousand projectiles is another.
We don't dumb things down to chase clicks. If a topic genuinely requires calculus to understand, we say so — and we teach the minimum you need.
PhysicsFundamentalsInfo is built by a small team of physics educators and writers committed to making science clearer for everyone. Our authors come from research backgrounds in mechanics, electromagnetism, thermodynamics, and modern physics, with combined teaching experience across universities and online platforms.
You can meet the authors who write for us. We're a young site, growing carefully — every article we publish goes through review before it goes live. We'd rather publish ten exceptional articles a year than a hundred mediocre ones.
After years of watching students struggle with poorly-explained physics, we decided to build the resource we wished existed when we were learning. The first article (Newton's Laws) took six weeks to write.
Site goes live with twelve articles across mechanics and thermodynamics. The first interactive lab — projectile motion — is published a week later.
We're publishing one new article every week, expanding the lab to cover more concepts, and growing a community of curious readers. Join the dispatch to follow along.
Our 2026-2027 roadmap includes: complete coverage of all classical physics fundamentals (we're about 30% there), interactive labs for every major concept, downloadable formula sheets for exam preparation, a comprehensive glossary, and eventually video walkthroughs of the hardest worked problems.
