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

Which object has elastic potential energy?

• a hanging leaf

• a burning coal

• a rolling ball

• a stretched bow

The diagram shows the same spring being stretched at different lengths using different masses. At which length does the spring have the MOST potential energy?

• length A

• length B

• length C

• length D

What is energy conversion?

• one type of energy changing to another type of energy
• energy in one object going into another object
• energy units changing
• energy units staying the same
