About this app
Physics Playground is a hands-on science app with 102 interactive physics labs, step-by-step learning paths, and Curiosity Lab, where you can ask your own science questions.
Every lab runs as a live simulation on your screen. You control it directly with your finger: drag the pendulum, aim the projectile, place charges in an electric field, change a wave's frequency, and watch the physics respond in real time.
HOW IT WORKS
Touch the canvas to grab and move the simulation. There is no right or wrong way to explore. Adjust gravity, mass, length, angle, and speed with the sliders and see the results change instantly.
For a hands-free experience, turn on the camera and control labs by moving your hand in the air. Hand tracking runs entirely on your device, and no images or videos are stored or sent anywhere.
102 LABS
Classic physics: pendulums, projectiles, collisions, springs, gravity, waves, the double slit, electric and magnetic fields, circuits, thermodynamics, fluids, quantum tunnelling, nuclear fission and fusion, orbits, and black holes.
How the World Works: everyday science you can notice at home and outside, such as colour mixing, shadows, bouncing balls, friction, ramps, seesaws, and parachutes.
Frontier labs: relativity, materials, energy systems, Earth science, and more.
ONE STEP AT A TIME
Short learning paths (Things that move, Light and sound, Earth and space) ask a simple question, like "Why do swings keep going?", and take you straight into the lab that answers it.
CURIOSITY LAB
Type or say any science question and get a short, clear answer, written for young learners and checked by safety rules. Hear it read aloud, tap "Draw it!" for a picture that explains the idea, and save the answers you like. Answers are generated by AI and can occasionally be wrong. You can report any answer with one tap.
CHALLENGES AND PROGRESS
Every lab has a built-in challenge that teaches the key idea behind it. Complete it to earn a star and track how many labs you have mastered on the Progress screen.
REAL PHYSICS LAWS
Each simulation is built on real equations, and the app shows the laws behind every lab so you can connect what you see to the formulas.
WHO IS IT FOR
Students, teachers, and anyone curious about how the world works. It suits middle school through university and is a great companion to classroom learning. No prior physics knowledge needed.
YOUR ACCOUNT
You can use everything as a guest. Sign in with Google if you want to keep your progress and saved answers when you change devices, and delete your account at any time from the app.
PRIVACY
The first time you open the app, you choose whether to allow usage analytics (Google Analytics for Firebase) and ad measurement (Meta, which helps us see which of our ads led to an install). Neither is used to show you ads, and you can change both at any time under Privacy choices on the Progress screen. Crash reports and a basic record of how the app is used are kept so we can fix problems and improve it.
