Physics Note M.4-6 Review: Visual Physics Notes and 1,000+ Problems
High school physics asks a lot at once: concepts, formulas, units and the skill of reading a problem correctly. If you are looking for a Thai high school physics study app that makes ideas visual, explains every formula and gives you real practice, Physics Note M.4-6 by ChatStick is built for exactly that.
The app is designed to feel like a colorful set of study notes passed down from a top senior student, with a friendly cat mascot as your daily study buddy. It covers 23 topic areas from mechanics to nuclear physics and includes more than 1,000 practice problems with step-by-step solutions. The content is written in Thai and follows the Thai upper secondary (Mathayom 4-6) curriculum.
Why physics feels hard for so many students
Most students do not struggle because they cannot memorize formulas. They struggle because they do not know which formula a question needs, and they cannot picture how forces, vectors or waves actually behave. Long blocks of text rarely fix that. What works better is learning through diagrams, practicing with solutions that explain the reasoning, and coming back to past mistakes in a structured way.
Physics Note M.4-6 is built around those three habits. Every chapter starts with a visual overview, every formula comes with context on when to use it, and every mistake you make is saved so you can fix the weak spot instead of repeating it. The result is a study routine that fits into short sessions on a phone or tablet, whether you have ten minutes on the bus or an hour before a test.
Key features
Visual summaries: short concept cards with original diagrams such as motion graphs, free-body diagrams, vectors, projectiles, waves, circuits and optics.
A mind map for every chapter: see the whole chapter on one screen and tap into subtopics across several levels.
Formula library: variables, units, when to use each formula and worked examples, searchable in Thai or English, plus a “which formula should I use?” helper.
1,000+ practice problems: sorted by chapter, grade and three difficulty levels (basic, standard, exam), each with step-by-step solutions, hints and common pitfalls.
Mistake notebook with spaced repetition: wrong answers are saved automatically and brought back at the right time.
Flashcards: flip through definitions, formulas and units.
Timed mock exams: prepare for A-Level and TCAS with results broken down by topic.
Progress tracking: XP, accuracy stats, streaks and achievements.
Works offline: no sign-up or login required.
What the 23 topic areas cover
Topics follow the high school physics sequence and finish with a dedicated A-Level review section.
Area | Topics in the app |
Mechanics | Mechanics, vectors, linear motion, Newton's laws, equilibrium, work and energy, momentum |
Motion | Projectile motion, circular motion, simple harmonic motion, gravitation |
Waves and light | Waves, sound, light |
Matter and heat | Fluids, heat and gases |
Electricity and magnetism | Electrostatics, electric current, electromagnetism, electromagnetic waves |
Modern physics | Atomic physics, nuclear physics, A-Level review |
How to get the most out of it
Open the mind map for the chapter you are studying to see its structure first.
Read the concept cards and diagrams, then check the formula library to understand every variable.
Start with basic problems, then move to standard and exam level. Read the solution even when you get it right.
Review the mistake notebook and flashcards when the app brings them back.
Before the real test, take a timed mock exam and use the topic breakdown to plan your revision.
Tip: a few problems every day, plus regular review of your mistake notebook, builds problem-solving habits far better than one long cram session.
