Bouncing balls: what is elasticity
Three balls fall from the same height but bounce differently. A simple physics experiment for kids 5+: elasticity, energy and rebound.
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.
Three balls fall from the same height but bounce differently. A simple physics experiment for kids 5+: elasticity, energy and rebound.
Galileo’s classic experiment, made interactive: a heavy and a light ball fall from the same height. Which lands first? Physics for kids 6+.
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+.
A heavy ball on a rod swings down and smashes a brick wall. An energy and momentum experiment for kids 7+.
Five bodies of different density drop into water: cork, wood, ice, brick and an iron ball. Which sink and which float?
A tablecloth is pulled fast and slowly. The first time the cups stay on the table, the second time they ride off and fall.
We drop an apple, ice, a potato, a fresh and an old egg into water. Who floats and who sinks? Density decides.
Three skiers ride down the same hill: with good wax, poor wax and none. Compare who glides farthest on the flat.
A locomotive pulls five wagons with slack couplings. They start not together but one after another — a wave of jerks.
Snowballs roll down a mountain. Rows of trees on the slope slow the avalanche so less snow reaches the house.
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.
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.
A sled and a cart get the same push. The sled quickly stops while the wheeled cart rolls much farther.
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 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 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.
Three identical swings: no pushes, pushes along the motion and pushes against it. Rules push the seat as it passes the lowest point.
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.
One project, 20 frames, each with the Tymora logo and its own physics: Moon, zero gravity, ice, pendulum, spring, water, dominoes and more.
