What this subsection covers
Point masses, spherical symmetry result, superposition, action-reaction pairs, and inverse-square scaling.A strong response uses field-vector diagrams and states where the model stops being reliable.

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.
