1.3.21 - Power, time and energy transfer

Use P = E/t and P = W/t to relate power, time, energy transferred and work done.

Use - power, time and energy transfer to connect the rule to the data and decision in the question.

This matters because - power, time and energy transfer determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - power, time and energy transfer to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Power, time and energy transfer is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
