Constant Motion Tracker

What does a motion graph actually measure?

Learnposition, velocity, and graph slope

DoDrag and launch carts, then compare position-time and velocity-time graphs.

WatchChanging speed changes slope and velocity readout.

Trajectory graph

BeforeStart by changing only launch angle. Watch the path and the graph peak before tuning anything else.

ActionSave prediction, then run the model.

AfterWaiting for a visible result.

Visible result

No run yet

The model will show cause and effect after you save a prediction and run it.

Step 3

Defend the object's motion using graph slope and velocity evidence.

Misconception signal

Common trap: higher graph means faster

Intervention

Mastery gate: Predict and defend motion from position, velocity, acceleration, and graph evidence.
