Force–displacement graphs

Signed areas, piecewise curves, experimental data, and graphical work estimates.

Course-map guide · not a complete lesson or simulation

Scope & orientation

What this subsection covers

Signed areas, piecewise curves, experimental data, and graphical work estimates.

A strong response uses energy-transfer diagrams and states where the model stops being reliable.

Reasoning checklist

Evidence, assumptions and limits

01

Assumptions to state

State the system, observable, approximation, and conditions held fixed before using a model.

02

Evidence to collect

Does measured net work predict the cart's kinetic-energy change?

Does measured net work predict the cart's kinetic-energy change? Useful evidence includes force-position data, numerical area, speed data, uncertainty, and percent discrepancy.

03

Limits to state

This GioPhysics course map is an adaptable teaching sequence, not a claim of accreditation or a universal university syllabus.

This GioPhysics course map is an adaptable teaching sequence, not a claim of accreditation or a universal university syllabus. Departments can adjust the order, mathematical depth, laboratory hours, and optional fluids endpoint to match local requirements. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
