Short explanation

Explain how lubrication reduces unwanted energy transfers by reducing friction. sits inside the Energy transfers in a system subtopic of Conservation and dissipation of energy for AQA GCSE Physics Energy. To revise it well, start by naming the relevant energy store, transfer pathway, equation or resource idea, then explain how the quantities connect in the question. Use precise Physics vocabulary from this objective, including lubrication, and keep closely related ideas distinct: energy is stored or transferred, power is the rate of transfer, and efficiency compares useful output with total input. In exam answers, state the principle first, substitute values only when needed, include units, and finish with a conclusion that links back to Energy transfers in a system.
