Scope & orientation

What this subsection covers

Mobile and bound charge, redistribution, polarization, grounding, and the microscopic limits of ideal material models.

A strong response uses vector force maps 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

Which observations distinguish charging by contact from charging by induction?

Which observations distinguish charging by contact from charging by induction? Useful evidence includes a controlled sequence, sign tests, charge conservation, repeat trials, and an evidence-based mechanism claim.

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.
