• The energy of an object has because of its motion.

Name the energy transformations taking place when I plug in my radio and it begins playing.

• Thermal to mechanical to electrical
• Radiant to chemical
• Electrical to sound

What is sound energy?

• The energy that an electric current carries. When you plug something in, this energy flows.
• Energy carried in waves of vibrating matter. It cannot travel through empty space (it MUST have matter to travel)
• Energy stored in objects that are compressed or stretched like springs or rubber bands.

Which items would have this energy transformation: mechanical energy -> sound energy?
