EPE, CPE, NPE, energy conservation & transfers

A stretched rubber band represents what type of potential energy?

• gravitational potential energy

• elastic potential energy

• chemical potential energy

• kinetic potential energy

Elastic potential energy is energy stored in an object, such as a spring, due to the object being stretched or compressed. In which position is it most likely that the spring has lost its elastic potential energy?

• W

• Y

• X

• Z
