Steps 1-3 Free Steps 4-6 Paid
STEP 1
Orient: one-dimensional potential wells
Free
Establish potential energy as a position-dependent energy-bookkeeping tool.
Prompt preview will appear here.
Goal: define potential energy using reference choice, changes, graph meaning, and units.
STEP 2
Conceptual grounding: build the potential-energy model
Free
Build a workflow for reference choices, graphs, slopes, allowed regions, and turning points.
Prompt preview will appear here.
Goal: connect U(x) graphs to energy changes, force direction, allowed regions, and turning points.
STEP 3
Real-world connection: interpret energy graphs and forces
Free
Apply potential-energy reasoning to gravity, springs, energy landscapes, and conservative-force previews.
Prompt preview will appear here.
Goal: explain reference choice, slope-force relations, potential wells, and conservative-force previews in physical contexts.
STEP 4
Check your understanding: diagnostic mini-quiz
Paid
Attempt each question before revealing the potential-energy reasoning.
Prompt preview will appear here.
Goal: identify and correct reference, slope-sign, graph-reading, and allowed-region errors before they become calculation errors.
STEP 5
Practice: solve increasingly rich potential-energy situations
Paid
Apply the model to situations that grow in complexity.
Prompt preview will appear here.
Goal: write concise, physically justified potential-energy-function explanations and solutions.
STEP 6
