Newton’s cradle: conservation of momentum
One ball strikes a row and exactly one ball swings out from the other end. An interactive Newton’s cradle — a lesson on momentum and energy.

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.

Pendulum wave: patterns from oscillations
Eight pendulums of different lengths swing together: first a travelling wave, then chaos, then order again. A 3D experiment for kids 9+.

Skate halfpipe: energy back and forth
A wheel rolls into a half-round ramp and climbs the other side almost to the same height. A chart shows the energy.

A weight on a spring: heavier means slower
Three weights of 0.25, 1 and 4 kg bob on identical springs. The light one is quick, the heavy one slow, and the chart shows the period.

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.

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.

A door on hinges and a door closer
Three doors get the same push. With no closer the door stays open, with a spring only it rushes back and bangs, and with a spring and a damper it closes smoothly.

Why a pyramid is stable and a tower is not
The platform sways from side to side. A tower of ten cubes falls almost at once while a pyramid of ten cubes stands.

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.
