M1.5.2 - Equilibrium of a particle under

Equilibrium of a particle under Only simple cases of the application of the conditions for coplanar forces.; Weight, normal equilibrium to uncomplicated systems will be required. reaction, tension and thrust, friction.

Use equilibrium of a particle under to connect the rule to the data and decision in the question.

This matters because equilibrium of a particle under determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply equilibrium of a particle under to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Equilibrium of a particle under is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
