Elastic Potential Energy

Physics: AQA GCSE Higher, topic 5.2.19

Work Done on a Spring

When a force stretches a spring or compresses another object, work is done. When this work is done, energy is transferred into an elastic potential energy store.

Compressing a spring

Compressing a spring

  • When we compress a spring, elastic potential energy is stored in the spring (so long as a spring isn’t inelastically deformed!).
Elastic potential energy stored

Elastic potential energy stored

  • The elastic potential energy stored in a spring is equal to the work done when stretching it.

Test yourself on Elastic Potential Energy

  • When work is done on a spring, what is stored in the spring?
