Talking about energy stores
Teaching Guidance for 11-14
Describing an elastic band
It may seem a bit of a mouthful in class to talk about:
Teacher: The elastic store of energy associated with the rubber band.
However, it would be perfectly acceptable to refer to:
Teacher: The elastic store of the rubber band.
… or to hold up the rubber band and say:
Teacher: Here we have a rubber band, an elastic store.
