Topic module

Pressure, Energy and Simple Machines

Apply basic pressure, energy-transfer and simple-machine principles to unfamiliar arrangements.

Long-form learning

Concept to Risk to Memory to Check-up

Build an accurate method first, add controlled pace second, and follow the instructions shown in the official assessment for every timed section.

Core concepts

Concept 1

Pressure

Exam cue: Identify what is conserved or transmitted, then compare the relevant area, height, distance or energy change.

Concept 2

Energy transfer

Exam cue: State the expected direction of change before calculating or comparing options.

Concept 3

Simple machines

Risk pitfalls and guardrails

Using a memorised relationship without identifying the system boundary or changed quantity.

Guardrail: Do not turn a broad public ability or familiarisation format into a claim about secure Royal Navy test content.
