Stretched Cord Energy Store
In a ride at a theme park, a person is strapped into a pod that is attached to two stretched bungee cords.
The bungee cords behave like springs.
Which energy store increases as the bungee cords are stretched?

- 1 Names the elastic potential energy store.
Full-mark answer
The elastic potential energy store increases.
Why this answer loses marks
The gravitational store increases while the cord is stretched.
The question focuses on deformation of the cord, so identify the store associated with stretching rather than height.
