Gravitational Sound Kinetic Thermal Electrical Radiant Nuclear/Atomic Mechanical Chemical Potential 1. This form of energy that living things can hear is associated with the vibration of matter. _____________________________ 2. This form of energy comes from the temperature of a heated substance or object. ______________________________ 3. This is energy an object has because of its position and motion. ______________________________ 4. This is generated by the movement of electrons. _______________________________ 5. This energy comes from the nuclei of atoms when they are split apart. ______________________________ 6. This is stored energy an object has because of its position. ______________________________ 7. This energy comes from the bonds of atoms and molecules when they interact with each other. _______________________________ 8. This is energy an object has because its moving. _____________________________ 9. This energy comes from electromagnetic waves like x-rays, gamma rays, and light rays. _______________________________ 10. This energy is stored in an object’s height and position. _______________________________
