13. Consider the Law of Conversion of Energy. Energy can be converted between different kinds. Think about a windmill providing energy to power the screen on our phones. What are the different forms of energy that we see in this system? A windmill --> to our houses, through a series of charging cables --> phone battery --> the phone (how many energies are in the phone?) (a windmill is mechanical energy first) *
