Physics Zen: Learn & Practice

Physics Zen turns physics into focused, repeatable practice. Work through fresh generated problems, check your answer instantly, and open the theory or worked solution exactly when you need it.

A COMPLETE PHYSICS PATH

Practice 57 skills across 19 topics:

• Mechanics: motion, forces, energy, momentum, rotation, oscillations, gravitation and fluids
• Electricity and Magnetism: electrostatics, circuits, capacitors, RC transients, magnetism and induction
• Waves and Optics: sound, standing waves, reflection, refraction, lenses, interference and diffraction
• Thermodynamics: heat, phase changes, gas laws and thermal efficiency
• Modern Physics: photons, atoms, radioactivity and mass-energy

EXAM PREP

• AP Physics 1 path aligned to the current eight-unit course
• AP Physics C: Mechanics path with calculus-based problems
• AP Physics 2 path across thermodynamics, electricity and magnetism, optics, waves and modern physics
• A-Level Physics path across the full in-app curriculum
• Focused Abitur Physik practice in fields, oscillations, wave optics and quantum physics
• French Bac physics practice; chemistry and the practical assessment are not included
• Japan's University Entrance Common Test: practice in the style of Physics and Basic Physics
• Korea's CSAT (Suneung) Physics I practice for the 2027 exam
• Korea's CSAT Integrated Science, 2028 exam onward: practice on its physics part
• Taiwan's Advanced Subjects Test (分科測驗) Physics, which also covers the physics in the GSAT (學測) science paper
• Exam-style multi-part questions and data interpretation
• Board-specific gravity conventions

Every item is original practice, not an official exam paper.

BUILT FOR PRACTICE

Generated Problems: Practise fresh parameter combinations across multiple difficulty levels.

Mastery Progression: A five-level bucket system moves from foundations to multi-step problems as you demonstrate understanding.

Theory Beside the Problem: Open concise explanations, formulas and worked examples without leaving your session.

Mistake Journal: Wrong answers are saved automatically. Retry the same concept later with fresh numbers.

Visual Physics: Graphs, force diagrams, circuits, waves, rays, energy levels and fluid scenes support the problems that need them.

Offline First: The curriculum and generator work without an internet connection. Optional sign-in adds cross-device sync.

Focused Interface: No ads, no coins and no lives. Includes light and dark themes.

Content is available in twelve languages: English, German, French, Spanish, Brazilian Portuguese, Dutch, Swedish, Japanese, Simplified Chinese, Traditional Chinese, Korean and Russian.

HOW IT WORKS

1. Choose a section, topic or exam path.
2. Solve a generated problem at your current level.
3. Check your answer and read the worked solution.
4. Build mastery and return to mistakes that need another pass.
