Energy in Action

Michael and Benjamin are having a debate. Michael says a glowing light bulb is an example of mechanical energy, while Benjamin argues that a moving car is. Aria, who is listening to them, thinks it's a hot cup of coffee or the sound of a guitar. Who is correct?

• A glowing light bulb

• A moving car

• A hot cup of coffee

• The sound of a guitar
