This mobile-friendly simulation offers a highly interactive way for learners to explore how graphs of position vs. time or velocity vs. time are related to real-world motion. In each exercise, the simulation provides a motion graph. The student's task is to build a ramp with the correct height and incline angles so the motion of the rolling ball matches the target graph. Adjustments can be made until the ramp configuration is an accurate match. Built-in "star" rewards create a game-like environment with incentives to keep going.
Editor's Note: This activity could be useful as a formative assessment. It can be adapted for a variety of learning levels from conceptual physics through AP Physics courses. It's fun, but challenging.
