Interactive Physics Experiments
Interactive physics simulations — learn by playing!
Balancing Act
Explore torque and balance by placing objects on a seesaw — can you predict what will tip?
PhET Simulation LaunchCircuit Construction Kit
Build circuits with batteries, resistors, light bulbs, and switches to explore electricity.
PhET Simulation LaunchEnergy Skate Park
Build a skate track and watch energy transform between kinetic and potential as a skater rides the rails.
PhET Simulation LaunchForces and Motion: Basics
Push and pull objects to explore forces, mass, and friction with this PhET simulation.
PhET Simulation LaunchGravity & Orbits
Create your own solar system — drag planets and watch gravity shape their orbits.
Interactive Sim LaunchNewton's Cradle
Watch momentum transfer in action — pull back a ball and release to see Newton's laws at work.
Interactive Sim LaunchProjectile Motion Simulator
Launch a projectile and explore how angle and velocity affect its path through the air.
Interactive Sim LaunchWave Interference Patterns
See how two wave sources create beautiful interference patterns of constructive and destructive waves.
