Item EG043005: For two identical springs, the spring that is compressed more has more elastic energy.
A student has two identical springs, Spring 1 and Spring 2. She compresses Spring 1 a little bit, and she compresses Spring 2 as much as she can.
While the springs are compressed, which spring has more elastic potential energy and why?
- Spring 1 has more elastic potential energy because the student can still compress it more.
- Spring 2 has more elastic potential energy because it is compressed more than Spring 1.
- Both springs have the same amount of elastic potential energy because they are identical springs.
- Neither spring has any elastic potential energy because springs only have elastic energy when they are stretched and not when they are compressed.
