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.

Propeller airplane: thrust and lift
Speed a 3D airplane up and take off: the propeller gives thrust, the wing gives lift. Flight physics for kids 9+.

Gears: the gear ratio
Gears with 12 and 24 teeth: the small one spins twice as fast, reversed. A gears experiment for kids 8+.

Belt and chain: transmitting rotation
Belt and chain like on a bike: rotation keeps its direction, speed depends on wheel size. For kids 8+.

Workshop: piston, spring and chain
A piston on key P, a weight on a spring and a ball on a chain in one 3D scene. Mechanics for kids 9+.

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.

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.

The shock absorber: keeping the body from bouncing
Two identical cars drive over bumps: the top one has only a spring, the bottom one a spring and a shock absorber. The top body bounces for a long time, the bottom one settles quickly.

Earthquake: a tall tower and base isolation
A crank mechanism shakes the platform. A narrow tower falls, a wide house stands, and the same tower on soft springs and dampers survives the shaking.

A mixer: gears and beater speed
One motor spins two beaters through gears: they turn against each other twice as fast as the motor and whip the “dough” in the bowl.
