Energy Changes in a System (AQA GCSE Physics): Flashcards

Energy stored in an object that is stretched or compressed

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

Elastic potential energy

Joules (J)

Spring constant

Newtons per metre (N/m)

Extension

Metres (m)

Linear until limit of proportionality

Point beyond which spring won't return to original length

Extension $\propto$ Force (proportional)
