3. Types of Energy

4. Potential vs. Kinetic Potential Energy Kinetic Energy Stored energy
Energy of motion

5. Forms of Energy

6. Mechanical Energy The total energy of motion and position of an object
Mechanical energy = potential + kinetic
Examples: rollercoaster, juggling

7. Thermal Energy
All of the kinetic energy due to random motion of particles that make up an object
Depends on speed & number of particles
Examples: boiling water, rubbing hands together

8. Chemical Energy Energy stored in the bonds of atoms & molecules
Examples: baking soda, fossil fuels

9. Electrical Energy Energy of moving electrons
Electrons are negatively charged particles
Examples: appliances

10. Sound/Acoustic Energy
Energy caused by the vibrations of an object
Examples: guitar, speakers

11. Light/Radiant Energy
Energy produced by the vibrations of electrically charged particles
Examples: sun, microwave, radio waves

12. Nuclear Energy
Energy that comes from changes in the nucleus of an atom
Examples: sun, uranium, hydrogen

13. Magnetic Energy Energy from the attraction of objects made of iron
Examples: magnets, generators
