STEP 1
Orient: connect forces to motion equations
Free
Establish the workflow from system choice and forces to acceleration and then motion over time.
Prompt preview will appear here.
Goal: determine acceleration from forces before choosing a motion equation.
STEP 2
Conceptual grounding: build the model
Free
Build a disciplined method for combining Newton's Second Law with kinematics under valid assumptions.
Prompt preview will appear here.
Goal: recognize when constant-acceleration kinematics is appropriate.
STEP 3
Real-world connection: interpret forces and motion
Free
Use carts, sleds, vehicles, falling objects, and multistage events to select the right model.
Prompt preview will appear here.
Goal: split a changing event into intervals with consistent force conditions.
STEP 4
