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?

  1. The girl’s rubber band has more energy because it is stretched more than the boy’s rubber band.
  2. 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.
  3. 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.
  4. Neither one of the rubber bands has any energy because the rubber bands are not moving.
