Motion and interaction
Adjust force and mass for a cart. Predict the acceleration vector before running each case, then compare position, velocity, and acceleration graphs over time.
What changed
Net-force setting 5 acts against mass setting 35. Acceleration follows their ratio, not either value alone.
Return to the route
Experiment after prediction.
Before changing a control, say which visible feature should move and which should remain invariant. That prediction is the useful part of the experiment; motion alone is not evidence.
