Misconception EGM034:

Elastic potential energy is the potential for an object to be stretched or compressed. For example, a rubber band has less elastic energy when it is stretched very far than when it is stretched a little bit because it can’t be stretched much more and a rubber band that is stretched a little bit has more elastic energy because it can be stretched a lot more (AAAS Project 2061, n.d.).

EG035005

The elastic energy of a spring increases when a student compresses it.

22%

EG044003

For two identical elastic objects, the object that has more elastic energy is stretched more.

18%

EG041004

For two identical rubber bands, the rubber band that is stretched more has more elastic energy.

18%

RG054003

A spring has more energy if it is compressed more.

18%

RG167002

Stretching a rubber band increases the amount of elastic potential energy because the distance between the molecules that make up the rubber band increases, and intermolecular forces act to restore the molecules to the unstretched distance.

17%

EG043005

For two identical springs, the spring that is compressed more has more elastic energy.

15%

RG052003

The more a rubber band is stretched the more energy it has.

15%

RG130002

Stretching a spring increases the elastic potential energy because the distance between the molecules that make up the spring increases, and forces between the molecules act to restore the molecules to their original separation.

14%

RG051003

A rubber band that is stretched more will travel farther when let go than a rubber band that is stretched less because the more a rubber band is stretched the farther it will travel.

13%

RG197001

The stronger the intermolecular forces, the greater the amount of elastic potential energy there is for a given length stretched.

7%

RG053003

A spring will jump higher if it is compressed more before letting go.

7%

EG040004

For two rubber bands stretched the same amount, the rubber band that was harder to stretch has more elastic energy.
