Electric potential and potential difference
Potential energy per unit charge, voltage, work, reference zero, units, and measurable differences rather than absolute values.

What this subsection covers
Potential energy per unit charge, voltage, work, reference zero, units, and measurable differences rather than absolute values.A strong response uses potential-versus-position graphs and states where the model stops being reliable.
Reasoning checklist
Evidence, assumptions and limits
Assumptions to state
State the system, observable, approximation, and conditions held fixed before using a model.

This GioPhysics course map is an adaptable learning sequence, not academic credit, accreditation, or a universal university syllabus. Departments may redistribute weeks, laboratory hours, optics, or the modern-physics survey to match local requirements. Thermal physics appears as an unnumbered institutional extension: some universities assess it within Physics II, while others teach it in a separate course, so include the thermal extensions only where the local syllabus requires them. A result should be checked against units, signs, limiting cases, and the conditions under which its model was derived.
