4. FORMS OF ENERGY: Mechanical: energy that moves an object.
Sound: energy caused by vibrations

5. Chemical: energy stored in chemical bonds.
Thermal (heat): energy from the movement of molecules.

6. Electromagnetic: transmitted through space in the form of waves
7 TYPES:
Radio waves
Microwaves
Infrared radiation
Visible light
Ultraviolet rays
X-rays
Gamma rays

7. Energy Transformations…
Occur when energy changes from one form to another.

8. MATCH: chemical energy → electromagnetic energy → thermal energy
Examples:
TV: electrical energy→ electromagnetic energy → sound energy → thermal energy
CAR: chemical energy → mechanical energy → sound energy → thermal energy
LIGHT BULB: electrical energy → electromagnetic energy → thermal energy
MATCH: chemical energy → electromagnetic energy → thermal energy
