Hello noodle brains! 1. what are the two most common types of potential energy? 2. is sound energy potential or kinetic? 3. what is energy that is stored in a rubber band? 4. what is mechanical energy? 5. is electromagnetic energy potential or kinetic? you!

1. chemical and  nuclear
2. Kinetic 
3. You input potential (stored) energy into the rubber band system when you stretchedthe rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy.
4. Mechanical energy is the sum of kinetic and potentialenergy in an object that is used to do work.
5. potential
