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.

Billiards: collisions and momentum
A cue ball breaks a rack on a top-down table. Momentum passes from ball to ball — a collision experiment for kids 8+.

A sensor opens the door: “if — then” logic
A ball rolls down a ramp and bumps a sensor, which turns green and removes the support under a second ball. Built from blocks.

A Rube Goldberg machine: a chain of events
A ball rolls down a ramp, topples dominoes, the last one hits a lever, which tosses a ball — and the ‘bell’ rings.

Robot vacuum: rules and touch sensors
A top view: the robot bounces off furniture and picks up crumbs. A touch sensor removes each crumb and timer rules change its course.
