STEP 2
Conceptual grounding: build the frame model
Free
Build a workflow for classifying frames and interpreting apparent effects.

Goal: explain when inertial analysis is preferred and when non-inertial language is being used.
STEP 3
Real-world connection: interpret observations safely
Free
Apply frame reasoning to elevators, buses, cars, rotating rides, and everyday observations.
Prompt preview will appear here.
Goal: connect sensations and observations back to real forces and acceleration.
STEP 4
