Specification 4.1.1.2 · Paper 1, Paper 2
Energy stored when an elastic object, such as a spring, is stretched or compressed.
Revise: Changes in energyStretching a spring transfers energy to its elastic potential energy store.
Use the elastic potential energy equation only if the spring has not exceeded its limit of proportionality.

Specification 15.6 · Paper 2
Energy stored in an object when it is stretched or compressed elastically.
Revise: Core Practical: Spring ExtensionProvided the spring remains elastically deformed and energy losses are negligible, the work done is stored as elastic potential energy.
Specification P2.2n, P2.3f, P7.1e · Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
Energy stored when an elastic object is reversibly stretched or compressed.
Revise: Stored energy calculationsFor example, a moving ball has a kinetic energy store, a raised object has a gravitational potential energy store, and a stretched spring has an elastic potential energy store.
Energy transferred to an elastic object when it is stretched or compressed, measured in joules (J).
Paper 1, Paper 2
Energy stored when an object is stretched or compressed and available to be released as it returns towards its original shape.
Revise: Work Done and Elastic Potential EnergyEnergy is transferred to the spring’s elastic potential energy store. If the spring returns to its original shape when released, stored energy can be transferred back to other stores, for example as the spring moves. Stretching too far may permanently deform it, so the work done will not all be recoverable as elastic energy.
