Free Physics Study Hub: Learn Physics Fast, One Bonk at a Time
From Newton's laws to light waves — free guides, decks and quizzes that make physics finally click.
What you'll learn
Physics explains why a curveball curves, why the sky is blue and why you slide forward when the bus brakes. The problem is that most physics resources either bury you in equations or skip the 'why' entirely. StudyBonk splits the difference: short, plain-English lessons, flashcard decks that drill the formulas, and quizzes that explain every answer.
Every page below is 100% free, works without an account, and saves your progress right in your browser. Earn XP, keep your streak alive, and turn the subject that confuses everyone into the one that finally makes sense.
- Describe motion with speed, velocity and acceleration
- Apply Newton's three laws to real situations
- Calculate kinetic and potential energy — and watch energy conserve
- Break down waves: wavelength, frequency and pitch
- Master Ohm's law and series vs parallel circuits
- Explain reflection, refraction, lenses and color
Every physics guide
Motion and Forces
Speed, velocity, acceleration and Newton's three laws — explained with skateboarders, not jargon.
Energy, Work and Power
Kinetic, potential, work and power — the ideas plus the four formulas that run them all.
Waves and Sound
Crests, wavelengths, frequency and the Doppler effect — waves finally drawn to make sense.
Electricity Basics
Charge, current, voltage, resistance and Ohm's law — the water-park analogy that makes it click.
Magnetism
Poles, fields, electromagnets and motors — magnetism from fridge magnets to fans.
Light and Optics
Reflection, refraction, lenses and color — light behavior from mirrors to rainbows.
