Steps 1-3 Free Steps 4-6 Paid
STEP 1
Orient: energy loss from non-conservative forces
Free
Establish conservative and non-conservative forces using work, path, and energy storage.
Prompt preview will appear here.
Goal: define conservative and non-conservative forces using path dependence, work, and energy.
STEP 2
Conceptual grounding: build the force-classification model
Free
Build a workflow for force classification, path dependence, closed loops, and dissipation.
Prompt preview will appear here.
Goal: classify forces and decide whether potential energy or dissipation language is appropriate.
STEP 3
Real-world connection: interpret paths, loops, and dissipation
Free
Apply the model to gravity, friction, drag, deformation, springs, and mechanical-energy conservation.
Prompt preview will appear here.
Goal: explain gravity, friction, energy loss, and mechanical-energy conservation in physical contexts.
STEP 4
Check your understanding: diagnostic mini-quiz
Paid
Attempt each question before revealing the conservative-force reasoning.
Prompt preview will appear here.
Goal: identify and correct path, loop, friction, and conservation errors before they become calculation errors.
STEP 5
Practice: solve increasingly rich energy-accounting situations
Paid
Apply the model to situations that grow in complexity.
Prompt preview will appear here.
Goal: write concise, physically justified conservative/non-conservative force explanations and solutions.
