4.3.89 - Centripetal acceleration derivation

Use vector diagrams to derive centripetal acceleration a = v²/r = rω² and apply these equations.

Use - centripetal acceleration derivation to connect the rule to the data and decision in the question.

This matters because - centripetal acceleration derivation determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - centripetal acceleration derivation to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Centripetal acceleration derivation is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
