5.6.158 - Gravitational potential in a radial field

Use Vgrav = −Gm/r for gravitational potential in a radial field.

Use - gravitational potential in a radial field to connect the rule to the data and decision in the question.

This matters because - gravitational potential in a radial field determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - gravitational potential in a radial field to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Gravitational potential in a radial field is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
