Item RG052003: The more a rubber band is stretched the more energy it has.
A girl and a boy find two rubber bands that are exactly the same. They each stretch a rubber band between their fingers. The girl stretches her rubber band as far as she can without breaking it. The boy stretches his rubber band a little less than the girl.
After the rubber bands are stretched, which one has more energy and why?
- The girl’s rubber band has more energy because it is stretched more than the boy’s rubber band.
- The boy’s rubber band has more energy because it can still be stretched farther, but the girl’s rubber band is stretched as far as it can go.
- Both rubber bands have the same amount of energy because the amount of energy a rubber band has is not related to how much it is stretched.
- Neither one of the rubber bands has any energy because the rubber bands are not moving.
