Equal to work done

A compressed or stretched spring

Possesses elastic potential energy

Elastic potential energy

Work done to compress or stretch an elastic material over a displacement

Elastic potential energy formula

Elastic potential energy

F=stretching or compression force, x=displacement from the equilibrium position

Elastic potential energy

Equal to work done
