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?

  1. Spring 1 has more elastic potential energy because the student can still compress it more.
  2. Spring 2 has more elastic potential energy because it is compressed more than Spring 1.
  3. Both springs have the same amount of elastic potential energy because they are identical springs.
  4. Neither spring has any elastic potential energy because springs only have elastic energy when they are stretched and not when they are compressed.
