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+.
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 blocks on an inclined plane: one slides like on ice, one slowly, one stays put. A friction experiment for kids 7+.
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+.
A drivable 3D car: keys W, S, A, D. Find out where the force that moves it comes from. Physics for kids 8+.
A cue ball breaks a rack on a top-down table. Momentum passes from ball to ball — a collision experiment for kids 8+.
A disk spins up with three balls at different distances from the center. Which flies off first? A rotation and friction experiment for kids 9+.
A tablecloth is pulled fast and slowly. The first time the cups stay on the table, the second time they ride off and fall.
Two ladders lean on a wall: the steep one stands, the shallow one slides. Find out why ladders are set at about 15°.
Identical salt shakers stand on trays tilted 10°, 20° and 35°. Find the angle where static friction no longer holds.
Three skiers ride down the same hill: with good wax, poor wax and none. Compare who glides farthest on the flat.
Two carts with dummies hit a barrier. The belted one stays put, the unbelted one flies forward.
Snowballs roll down a mountain. Rows of trees on the slope slow the avalanche so less snow reaches the house.
A sled and a cart get the same push. The sled quickly stops while the wheeled cart rolls much farther.
Two machines spin a drum with laundry. In the left one the load is spread evenly and the machine stays, in the right one it is in a single lump and the machine creeps across the floor.
Three identical cars with locked wheels slide at the same speed on dry asphalt, wet asphalt and ice. The stopping distance on ice is eight times longer.
