Elastic Potential Energy (OCR GCSE Physics A, Combined (Gateway Science Suite)): Flashcards

Energy stored in an object that is stretched or compressed

A force

Doing work

Elastic potential energy

$E_e = \frac{1}{2} \times k \times e^2$

Elastic potential energy (J)

Spring constant (N/m)

Extension (m)

Extension (m)

Force applied (N)

Linear relationship (until limit of proportionality)

Extension ∝ Force (proportional)

Spring won't return to original length if force too great
