Item EG041003: For two identical rubber bands, the rubber band that is stretched more has more elastic energy.
A student has two identical rubber bands. She stretches each rubber band around two pegs so that one rubber band is stretched a little bit and the other rubber band is stretched a lot.
When the rubber bands are stretched, which rubber band has more elastic energy?
- The rubber band that is stretched a little has more elastic energy.
- The rubber band that is stretched a lot has more elastic energy.
- The rubber bands have the same amount of elastic energy no matter how much they are stretched.
- Neither rubber band has any elastic energy.
