M1.5 - Statics of a particle

Forces treated as vectors.; Resolution of forces.

Use forces treated as vectors to connect the rule to the data and decision in the question.

This matters because forces treated as vectors determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply forces treated as vectors to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: Forces treated as vectors is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.

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.

Use the coefficient of friction and the equilibrium condition F ≤ μR.

Use coefficient of friction to connect the rule to the data and decision in the question.

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

Example: apply coefficient of friction to one small, clearly defined case, show the key step or comparison, and explain the result in words.

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