Steps 1-3 Free Steps 4-6 Paid
STEP 1
Orient: model tension in ropes and cables
Free
Establish tension as a pulling contact force exerted by a taut connector.
Prompt preview will appear here.
Goal: draw tension along a taut rope or cable and away from the attached object.
STEP 2
Conceptual grounding: build the force model
Free
Build a rope-direction and ideal-string-assumption workflow for FBDs.
Prompt preview will appear here.
Goal: identify when ideal-string assumptions permit equal tension through rope segments.
STEP 3
Real-world connection: recognize the force in context
Free
Apply tension reasoning to hanging objects, angled cables, connected carts, and pulley systems.
Prompt preview will appear here.
Goal: distinguish tension from other upward or contact forces.
STEP 4
Check your understanding: diagnostic mini-quiz
Paid
Attempt each question before revealing the force-model reasoning.
Prompt preview will appear here.
Goal: identify and correct force-source, direction, or condition errors before they become equation errors.
STEP 5
Practice: model increasingly rich force scenarios
Paid
Apply the model to scenes that grow in complexity.
Prompt preview will appear here.
Goal: produce clear, physically justified force models.
