Simple Forces

Choose an investigation, predict the system behavior, run the simulation, then connect motion, force, energy, or waves to evidence.

A rink, a puck, a trail

Push the puck and read the dots it leaves behind. The spacing of the trail is the speed; how the spacing changes is the force. Commit a prediction before every run. The evidence panel keeps everything.

Choose a mission to open its prediction gate.
