5.6.156 - Newton’s law of universal gravitation

Use Newton's law of gravitation F = Gm1m2/r².

Use - newton’s law of universal gravitation to connect the rule to the data and decision in the question.

This matters because - newton’s law of universal gravitation determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - newton’s law of universal gravitation to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Newton’s law of universal gravitation is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
