1. Energy Transformations

2. 2 Main Types of Energy
Kinetic Energy: the energy of motion (faster-more)
Potential Energy: stored energy (based on position, higher-more)

3. The Law of Conservation of Energy
Energy cannot be created
Energy cannot be destroyed
It can be transferred from one form to another.
Thus, when the water at the top of the waterfall plunges over the edge, potential energy is converted to kinetic energy.

4. Energy Transformations
As plates push against each other stress builds (potential energy).
When the plates move or break the energy is released as kinetics energy.

5. Major types of energy…
Chemical
Radiant
Thermal
Nuclear
Mechanical
Electrical

6. Chemical Energy Energy stored in matter because of its chemical makeup
Examples: Food, wood, fossil fuels (gas, coal, oil), battery
Potential
Energy

7. Radiant Energy Energy carried by electromagnetic waves
Examples: Light, microwaves, X-rays, Sun, radio, satellite
Kinetic
Energy

8. Thermal (Heat) Energy Energy related to the temperature of a substance
Examples: moving particles
substances – the higher the temperature the faster the particles move.
Kinetic
Energy

9. Nuclear Energy Energy stored in the nucleus of an atom
Examples: splitting of an atom
Potential
Energy

10. Mechanical Energy
Sum of total energy of matter because of its motion or position
Examples: wind, moving water, falling rocks, stretched spring, machines
Kinetic
Energy

11. Electrical Energy Energy produced by electric charges
Examples: electricity, lightning
