M3.4.3 - Uniform motion of a particle

Uniform motion of a particle Problems involving the ‘conical pendulum’, an elastic moving in a horizontal circle. string, motion on a banked surface, as well as other contexts, may be set.

Use uniform motion of a particle to connect the rule to the data and decision in the question.

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

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

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