Which term describes energy stored in a device before use?

• A. Kinetic energy
• B. Electrical energy
• C. Sound energy
• D. Chemical energy

Answer: (D)

Energy can show up in different forms, and the form that sits stored in a device before you use it is chemical energy. Think about a battery: the energy is held in the chemical bonds inside the battery and isn’t active yet. When the device is turned on, that chemical energy is released and often becomes electrical energy to power the gadget. Kinetic energy is the energy of something that is moving right now, not energy waiting to be used. Electrical energy is the energy of moving electric charges, which is what you get after the chemical energy is released. Sound energy is energy in the form of vibrations that make noises. So the energy stored in a device before you use it is chemical energy.
