Forces, motion, and pressure
Physics and Matter
This cluster is about patterns that look dramatic at human scale but still reduce to force, motion, and energy bookkeeping.
Explainers
Pages in Physics and Matter
Airflow, magnetism, orbits, sound, and shock waves showing how forces become visible consequences.
A magnet lab that lets you vary field strength, distance, material response, and pole setup to compare strong pull, weak response, and outright repulsion.
Physics and Matter What causes a sonic boom?A sonic-boom lab that lets you push speed past Mach 1, change altitude, thicken the air, and sharpen maneuvers to compare shock strength and ground impact.
Physics and Matter How do airplanes fly?A flight lab that lets you change airspeed, wing angle, air density, and wing shape to see when lift beats drag and when the wing runs out of margin.
Physics and Matter Why does metal rust?A corrosion lab that lets you change moisture, oxygen, salt, and coating damage to see when iron stays stable and when it begins to crumble into rust.
Physics and Matter Why do bubbles form spheres?A bubble lab that lets you adjust soap mix, inflation, airflow, and crowding to see when a bubble stays round and when foam geometry takes over.
Physics and Matter How does a compass work?A compass lab that lets you tune field strength, interference, latitude, and needle friction to see when the needle locks on and when it starts lying to you.
