Physics experiments
Interactive experiments for kids, students and teachers. Run each one right on the page, then open a copy in the Tymora editor and change mass, friction, elasticity or gravity. Every experiment comes with discussion questions and a version to try at home.

Heavy and light: do they fall the same?
Galileo’s classic experiment, made interactive: a heavy and a light ball fall from the same height. Which lands first? Physics for kids 6+.

Ramp and friction: ice, wood, rubber
Three blocks on an inclined plane: one slides like on ice, one slowly, one stays put. A friction experiment for kids 7+.

Chain reaction: falling dominoes
A ball pushes the first domino and a wave of falling runs through the whole row. An energy and chain reaction experiment for kids 5+.

3D block tower: stability and impact
A 3D tower of blocks and a heavy ball crashing into it. Orbit the camera and see why the tower falls. Physics for kids 6+.

Slope race: rolling or sliding
A sphere, a cylinder and a cube go down the same slope. Who wins — the roller or the slider? A 3D experiment for kids 7+.

Wrecking ball: energy of motion
A heavy ball on a rod swings down and smashes a brick wall. An energy and momentum experiment for kids 7+.

3D bowling: strike the pins
A heavy ball rolls down a lane and knocks over ten pins. A 3D momentum and collision experiment for kids 6+.

Sink or float: buoyancy
Five bodies of different density drop into water: cork, wood, ice, brick and an iron ball. Which sink and which float?

The tablecloth trick: inertia
A tablecloth is pulled fast and slowly. The first time the cups stay on the table, the second time they ride off and fall.

What sinks in the pot: apple, potato, egg
We drop an apple, ice, a potato, a fresh and an old egg into water. Who floats and who sinks? Density decides.

Skis and wax: who glides farthest
Three skiers ride down the same hill: with good wax, poor wax and none. Compare who glides farthest on the flat.

A train starts: why the wagons jerk one by one
A locomotive pulls five wagons with slack couplings. They start not together but one after another — a wave of jerks.

An avalanche and a protective forest
Snowballs roll down a mountain. Rows of trees on the slope slow the avalanche so less snow reaches the house.

A shot at goal: score, crossbar or over
Three balls fly at the goal with different speeds: one into the net, one off the crossbar, one over. The net turns green on a goal.

Sorting by size: a sieve
Small and large balls pour onto a tilted grate. The small ones drop into the left bin, the big ones roll on to the right.

Wheel versus sled: why a cart is easier
A sled and a cart get the same push. The sled quickly stops while the wheeled cart rolls much farther.

Trampoline: springs give the energy back
The same ball falls onto the floor, a soft trampoline and a stiff one. On the floor it stops dead; on the trampolines it bounces up again.

A jump on the Moon: six times higher
A boy jumps at the same speed as on Earth, but gravity here is lunar (1.62 m/s²). Marks show the jump height on Earth and on the Moon.

A lever: a child lifts a heavy stone
A 20 kg load on the long arm lifts a 50 kg stone when the fulcrum is close to the stone. With the fulcrum in the middle the stone stays put.

Swings: push in rhythm
Three identical swings: no pushes, pushes along the motion and pushes against it. Rules push the seat as it passes the lowest point.

A business card that falls apart: design meets physics
A neat business card built from 32 tiles, each with its own physics body. Press “Run” and the layout crumbles and drops to the floor.

The Tymora logo in 20 frames: twenty kinds of physics
One project, 20 frames, each with the Tymora logo and its own physics: Moon, zero gravity, ice, pendulum, spring, water, dominoes and more.
