Mechanics
Two Cart Race
Set mass and force for two carts. Newton's 2nd Law decides the winner.

Mechanics
Free Fall
Drop a ball under configurable gravity — Moon, Mars, Earth, Jupiter — and graph its speed and distance fallen in real time.

Mechanics
Galileo's Ramps
Release a ball on one incline and it climbs back to the same height on the other. Lay the far side flat and it never stops.

Mechanics
Newton's Third Law
A bug hits a windshield. Equal forces, very unequal accelerations: Ma = F = mA.

Mechanics
Impulse & Momentum
Hard and short or gentle and long: F·Δt = m·Δv. Then crash carts that stick and watch total momentum hold.

Waves
Wheel Refraction
Two wheels on an axle cross from fast to slow surface. The leading wheel slows first and the system bends — a mechanical model of Snell's law.

Waves
Wave Basics
Transverse and longitudinal waves with a tracked particle. Tune frequency, wavelength, and amplitude live.

Waves
Beats
Two notes of almost the same pitch swell and fade. See both waves and their sum, and hear the beats.

Waves
Doppler Effect & Shock Waves
Waves bunch up ahead of a moving source. Push it past the wave speed and they stack into a shock cone.

Optics
Reflection Simulator
Drag a flashlight and measure angles of incidence and reflection against a protractor.
Open →
Optics
Laser Refraction
Drag a laser pen around a circular water tank. Snell's law bends the beam; push the angle far enough and total internal reflection snaps it back.

Optics
Color Mixing
Mix red, green, and blue lights to see how additive color works. All three together make white.

E&M
Charge vs. Voltage
Two boxes at the same voltage light identical bulbs. The bigger box holds more charge, so its bulb stays lit longer.

Simple Circuits
Wire a battery, switch, and lamp in a drag-and-drop circuit builder.

E&M
Magnet & Compass
Move a bar magnet and a compass around the table. The needle swings to follow the magnetic field.
Open →
E&M
Magnetic Domains
Drag bar magnets into a field meter. Watch disordered domains align into a stronger permanent magnet.

E&M
Which Magnetic Pole?
Slide a known magnet and watch compass needles pivot to identify the unknown poles.
