Think about the human ear as it is listening to music or collecting sound. Human ears have an ear drum and three small bones. The bones are connected to the ear drum and when moving they are a form of ____________ energy from the drum and bones into electrical energy that follows your nerves into your brain. The answer is not a major category!
What is mechanical energy? Your eardrum and small bones moving are a form of mechanical energy. Sound enery

Electricity moves through which of the three parts of an atom?
What are the electrons?
300
Plants take this form of energy and turn it into sugar through the process known as photosynthesis. The process also uses water and carbon dioxide.
What is radiant or electromagnetic energy?
300
The major category of energy associated with motion.
What is kinetic energy?
