Rearrange energy equations to find mass, speed, spring constant, extension, gravitational field strength or height where appropriate.

Rearrange energy equations to find mass, speed, spring constant, extension, gravitational field strength or height where appropriate. sits inside the Changes in energy subtopic of Energy changes in a system, and the ways energy is stored before and after such changes 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 mass, speed, spring constant, extension, 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 Changes in energy.
