Steps 1-3 Free Steps 4-6 Paid
STEP 1
Orient: toward potential energy
Free
Establish the relationship between net work and kinetic-energy change.
Prompt preview will appear here.
Goal: define the work-energy theorem using net work, kinetic energy, and units.
STEP 2
Conceptual grounding: build the work-energy model
Free
Build a workflow for states, work terms, signs, net work, and speed change.
Prompt preview will appear here.
Goal: identify all work contributions and connect their sum to kinetic-energy change.
STEP 3
Real-world connection: interpret net work and speed change
Free
Apply work-energy reasoning to pushes, friction, stopping, ramps, and conservative-force previews.
Prompt preview will appear here.
Goal: explain speed, stopping distance, unknown force, and conservative-force previews in physical contexts.
STEP 4
Check your understanding: diagnostic mini-quiz
Paid
Attempt each question before revealing the work-energy reasoning.
Prompt preview will appear here.
Goal: identify and correct net-work, sign, missing-force, and speed-relation errors before they become calculation errors.
STEP 5
Practice: solve increasingly rich work-energy situations
Paid
Apply the model to situations that grow in complexity.
Prompt preview will appear here.
Goal: write concise, physically justified work-energy theorem solutions.
