Science / Physics
Understand
how the universe works.
Explore motion, matter, energy, waves, fields, light, and the fundamental laws that connect them. Physics here is designed to be understood, visualized, and eventually explored through interactive experiments.
Learning path
Build your understanding from motion and forces to fields, waves, light, and modern physics.
Mechanics
Motion, forces, Newton's laws, momentum, work, and energy.
↗ 02Gravitation
Gravity, gravitational fields, orbits, and planetary motion.
↗ 03Matter & Fluids
Density, pressure, elasticity, buoyancy, and fluid behaviour.
↗ 04Thermal Physics
Temperature, heat, expansion, gases, and thermodynamics.
↗ 05Waves & Oscillations
Vibrations, wave motion, sound, resonance, and oscillations.
↗ 06Electricity & Circuits
Charge, current, voltage, resistance, and electrical circuits.
↗ 07Magnetism & Electromagnetism
Magnetic fields, forces, induction, and electromagnetic effects.
↗ 08Optics
Reflection, refraction, mirrors, lenses, and optical systems.
↗Explore further
Go beyond the classical foundations and explore the ideas that changed our understanding of reality.
Modern Physics →
Relativity, quantum ideas, atomic physics, nuclear physics, radioactivity, and the foundations of the modern view of nature.
Quick referencePhysics Formula Sheet →
A compact collection of important equations organized by topic for quick revision and problem solving.
Don't just read the laws. Experiment with them.
The Physics Lab will eventually let you change variables, observe results, run experiments, and explore physical systems interactively. Mechanics, waves, circuits, optics, and more will become experiments rather than static diagrams.
