Classical Mechanics
x = v₀cosθ·t

Gravity Lab

Beginner

Projectile motion mastery

Launch projectiles, manipulate gravity, and solve 9 increasingly complex puzzles. Real kinematics — every shot follows actual equations.

Projectile motion · Elastic collisions · SHM · Air drag

Play Now
Gravitation
v = √(GM/r)

Orbital Mechanic

Intermediate

Master orbital velocity

Launch satellites into stable orbits. Too fast and you escape — too slow and you crash. Discover Kepler's laws through direct control.

Orbital velocity · Kepler's laws · Gravitational force

Play Now
Waves & Oscillations
T = 2π√(L/g)

Pendulum Master

Beginner

Swing through harmonic motion

Control pendulum length and release angle to knock targets. Multi-pendulum chains reveal resonance, energy transfer, and period independence.

Simple harmonic motion · Period · Energy conservation

Play Now
Classical Mechanics
m₁v₁ + m₂v₂ = const

Collision Lab

Intermediate

Elastic & inelastic impacts

Set mass, velocity and elasticity — then land balls in exact target zones using momentum transfer. Elastic to perfectly inelastic collisions.

Conservation of momentum · Kinetic energy · Restitution

Play Now
Waves & Optics
y = A·sin(kx − ωt)

Wave Interference

Intermediate

Superposition & resonance

Place wave sources on a 2D field and watch interference patterns emerge. Hit the resonance zone using constructive interference.

Wave superposition · Interference · Frequency · Amplitude

Play Now
Thermodynamics
KE = ³⁄₂kT

Thermal Escape

Advanced

Heat particles to escape velocity

Control the temperature of a gas — particles must reach escape velocity to break free. Watch Maxwell-Boltzmann distributions shift.

Kinetic theory · Maxwell-Boltzmann · Thermal velocity

Electromagnetism
V = IR · P = IV

Circuit Builder

Intermediate

Voltage, current & resistance

Drag and connect resistors, capacitors, and batteries to light up bulbs at target voltage. From basic Ohm's law to RC circuit puzzles.

Ohm's law · Series/parallel · Power dissipation

Play Now
Waves & Optics
n₁sinθ₁ = n₂sinθ₂

Optics Puzzle

Advanced

Bend light to hit the target

Place mirrors, prisms and lenses to redirect a laser to a target. Reflection, refraction and focal length puzzles up to multi-lens systems.

Snell's law · Reflection · Lens equation

Play Now
Kinematics
v_t = √(2mg / ρC_dA)

Free Fall Race

Beginner

Terminal velocity & drag

Drop objects of different shapes and densities in air or vacuum — predict landing order. Adjust drag coefficient to reach the target time.

Free fall · Terminal velocity · Drag force · Stokes' law

Classical Mechanics
KE + PE = E_total

Energy Converter

Advanced

Conservation of energy puzzles

Route a ball through ramps, springs, and heights to arrive at the exit with exactly the required energy. Every joule is conserved — or lost to friction.

Physics Education Games

Learn physics by playing it

Every game here runs on real physics equations — not approximations, not cartoon physics. When your satellite stabilises at the right altitude, you have understood Kepler's third law. When your pendulum hits every target, you have felt what period independence really means.

Why physics games work

Traditional physics education asks you to memorise equations first and build intuition second. Physics games invert this — you develop physical intuition through dozens of interactive experiments, and equations become a natural language for something you have already felt.

Each game here is designed around a single core concept, introduces it through play across 8–10 levels, then links to the full article where the mathematics is derived and explained.

Frequently asked questions

Are all games free?
Yes — completely free, forever. No account, no subscription, no ads. Physics Fundamentals is a free educational platform.
Do they work on mobile?
Yes. Every game has full touch support and responsive layout. Any modern browser on phone, tablet or desktop works.
Are the physics simulations accurate?
Every simulation uses real physical equations — the same ones taught in high school and university physics. Values are scaled for gameplay but the relationships between variables are exact.
What physics knowledge do I need?
None to start. Beginner games assume zero prior knowledge. Intermediate and Advanced games build on intuition from the earlier ones.
Can I use these in a classroom?
Yes — each game page includes full physics explanations, equations, and article links. They are designed to complement physics courses at high school and introductory university level.
