Physics simulations

Last updated: 16 October 2026

Every physics lab in Taz, grouped by topic. Each one is a 3D scene where you change one thing, predict what will happen and then watch it play out.

Forces and motion

Bouncing Balls: Drop a rubber ball from 30 cm. How high does it come back?
Bungee Toy: Hang a toy on a big spring and let go. Does a heavier toy bounce faster or slower?
Crashing Carts: Two carts crash on a track. Where does the push go?
Double Pendulum Twins: Release two double pendulums almost exactly the same. How long do they stay twins?
Friction Drag Test: Pull a block with a newton meter. How hard do you have to pull on ice, wood or sandpaper?
Projectile Launcher: Aim the launcher and fire a marble. Which angle sends it furthest?
Pulleys and a Newton Meter: Lift a brass weight with one wheel, then with more. How hard do you have to pull?
Rolling Race: Race a ball, a cylinder, a hoop and a hollow ball down a ramp. Which one wins?
Roundabout Ride: Spin the roundabout. How hard must the spring pull to keep the toy going round?
Ruler See-saw: Hang brass weights on a ruler. Can a light weight far out balance a heavy one close in?
Simple Pendulum: Time one swing. What changes it: the string, the bob, or the push?
Slide and Light Gates: Let a toy sled slide down a slide. How fast does it pick up speed?

Beat Frequency: Two nearly equal notes together go loud, soft, loud, soft. How fast is the wobble?
Diffraction Patterns: Ripples squeeze through a gap. Do they fan out or go straight?
Doppler Effect: A moving dipper squashes its ripples in front and stretches them behind.
Resonance: Shake three toys on springs gently. Why does only one go wild?
Sonar & Echolocation: Ping the water and listen. How long until the rock answers?
Sound Waves: A speaker squeezes the air. Watch the squeezes march across the stage.
Standing Waves: Buzz a cord at just the right rate and it splits into still points and big loops.
Wave Interference: Two dippers, one duck. Where do the waves add up, and where do they cancel?
Wave Motion: Shake one end of a cord. How fast does the wave run, and how long is each wave?
Wave Reflection: Ripples hit a tilted wall. Which way do they bounce?

Bending Light: Shine a ray into a glass block. How much does it bend?
Candle, Lens and Screen: Slide the screen until the candle is sharp. Why is its picture upside down?
Glowing Glass Rod: Shine a laser into a bent glass rod. Does the light follow the bend?
Prism Rainbow: Split white light into a rainbow with a glass prism.
Rainbow and Beyond: Slide from ultraviolet through the rainbow to infrared. Which light makes the star glow?
Sunglasses Test: Two polarising filters, one lamp. Turn one filter: where does the light go?

Bike Dynamo: Pedal a bike on a stand. How does turning a magnet light the lamp?
Charge the Flash: Fill a capacitor from a battery. Why does the light start bright and then fade?
Electric Fields: Charge a metal ball and hang a tiny pith ball beside it. How far does the invisible push move it?
Magnet Drop: Drop a magnet through a coil of wire. Can a falling magnet make electricity?
Magnet and Compasses: Slide a magnet and compasses round a desk. Which way do the needles point, and why does a far one wobble slowly?
Power to the Town: Change the turns on a transformer. Can you make the street lamps brighter, or blow them?
Scrapyard Crane: Switch on the crane magnet. How many cans can it grab, and how do you make it stronger?
Simple Circuits: Close the switch. What makes the bulbs brighter: more volts, fewer bulbs, or a different wiring?
Storm over the Town: Where will the lightning strike? Watch it feel its way down, then add a lightning rod.
Radio Mast to House: Send radio waves across town. How fast do they arrive, and why is the far house quieter?

Aerodynamics: Blow air over a wing. How fast before it lifts its own weight?
Bridge Stress: How can a bridge of thin sticks hold a heavy load? Which sticks are pulled, and which are squashed?
Gear Mechanisms: Big gear, small gear: which one turns faster, and why?
Heat Transfer: Bridge hot water and cold with a metal bar. Which metal carries heat best?
Hydraulics: Push a little piston gently. Can the oil lift a heavy crate?
