Physics
Pushes, pulls, energy and waves — physics is how the world moves. Learn each idea, then teach it back.
🔬 LAB · PLAY, THEN TEACH IT
Forces & Motion
Push boxes, play tug-of-war, feel friction — watch how forces make things move.
Opens in a new tab · a hands-on lab from PhET · University of Colorado Boulder. Play with it, then come back and teach it to your AI student.

The Force of FrictionRubbing between surfaces slows things down, so a ball rolls farther on smooth ice than on rough grass.Teach it →The Pull of GravityAn invisible pull from the Earth makes every dropped thing fall down instead of up.Teach it →Balanced and Unbalanced ForcesWhen two pushes cancel out nothing moves, but when one side wins — like in tug-of-war — things start to move.Teach it →The LeverA stiff bar resting on a pivot point lets a small push lift something heavy, like a seesaw lifting a big kid.Teach it →The Inclined PlaneSliding something up a long slope takes less push than lifting it straight up — that's the trick of the ramp.Teach it →Wheels and PulleysWheels cut down friction and pulleys change the direction of a pull, so one rope can hoist a flag or a heavy load.Teach it →
